QDoes TOYOFUSSO-E Hose for antistatic use require grounding on the clamp also?
A

Yes. Be sure to ground or bond the hose clamp. Failure to ground may cause the hose clamp to become an isolated conductor, accumulating static electricity and leading to electrical discharge or ignition.
Note that hoses with an antistatic band on the hose exterior (TOYOTOP-E Hose, TOYOTOP-E 100°C Hose, and TOYOFOODS EARTH Hose) are designed with a structure that does not generate static electricity on the surface of the hose (to a degree that static electricity could accumulate on the clamp).

QSome hoses are marked “R2” and others “RoHS2”. What is the difference?
A

Both markings indicate compliance with RoHS2. Toyox began marking RoHS2-compliant hoses with “R2” beginning with products produced in 2017. However, we switched later on that same year to printing “RoHS2” in order to clarify the meaning.

QAre your silicone hoses compliant with Food Sanitation Act No. 196 (PL System)? Can you provide a certificate of compliance?
A

Food Sanitation Act No. 196 (PL System) applies to synthetic plastic. This does not include silicon rubber. Toyox silicone hoses are compliant with Food Sanitation Act No. 595. Certificates of compliance are available for download by registered members (free).

QMy PVC transparent hose has turned white and cloudy. Should I replace it?
A

If this is caused by the water supply (devitrification), drying and removing moisture will return its transparency.

QIs a plane figure available for KAMLOK?
A

PDF drawings are available for download from the product page.
CAD drawings are available for download by registered members (free).

QMy TOYOFUSSO Hose does not have a line printed on it like the products shown on your website. Is there any difference in performance?
A

We switched the outer material for TOYOFUSSO Hose from soft PVC to polyurethane beginning with products produced in November 2018. Products since then have a line (image line) printed on them. This improved heat resistance performance from 70°C to 80°C

QWhat is the working temperature range of KAMLOK?
A

The working temperature range of KAMLOK depends on that of the gasket. With that said, the maximum working temperature for KAMLOK models made from polypropylene (PP) is 60°C.

QIs the flange in the KAMLOK with Flange set compliant with JIS 10K?
A

Models such as the KAMLOK 633LAS and 633LBS have a flange that is compliant with JIS 10K.

QWhen attaching a hose to a nipple with a clamp, where should the clamp be placed?
A

To securely connect the parts, fasten the clamp in the middle of the peak of the barb, above the depression. Do not fasten it immediately below the hexagonal area of the nipple. We recommend using two clamps if the hose size is greater than 1″ (25mm).

QCan a 1/2″ coupler be connected to a 3/4″ adapter?
A

Yes, it can. The fitting areas of the 1/2″ coupler and 3/4″ adapter are the same size. Likewise, a 3/4″ coupler can be connected to a 1/2″ adapter.

QWhat is the working pressure range of KAMLOK?
A

It varies depending on the body material and size. Click here for reference information on working pressure ranges.
With that said, the working pressure of the hose needs to be taken into account when connecting the hose. Please also be aware that even if the pressure applied is within the working range of the hose, pressure may be released if depending on the clamps situation.

QHow do I attach the fall prevention chain (sold separately) to the KAMLOK 634-B (dust cap)?
A

Use the round connecting hole or the ring at the end of the arm.

QWhy can’t I use hot water over 100 ℃ for TOYOSILICONE Hose?
A

Due to the characteristics of the TOYOSILICONE Hose, it is a material with higher gas permeability (porous) than vinyl hoses. If high-temperature water exceeding 100 degrees is used, the steam of the high temperature water will permeate the inner pipe of the hose, which may easily damage the reinforcement thread and reduce the hose pressure resistance performance. The hose that can flow hot water up to 140 ° C is the TOYOSILICONE Steam Hose.

QWhat is the difference between TOYORON Hose, SUPER TOYORON Hose, and HYPER TOYORON Hose?
A

The difference between TOYORON Hose and SUPER TOYORON Hose is the difference in oil resistance of the hose outer skin, and SUPER TOYORON Hose is more oil resistant. HYPER TOYORON Hose is a hose that is more oil resistant to the inner tube and outer skin than TOYORON Hose and SUPER TOYORON Hose.

QWhich is the operating temperature range of the hose, inside or outside the hose?
A

The operating temperature range of the hose is both the fluid temperature and the atmospheric temperature.

QI would like to know the subsequent product to the W-SAFETY Nipple Set (WFSN).
A

The W-SAFETY Nipple Set (WFSN) will be discontinued. The subsequent product will be TOYOCONNECTOR couplings (dedicated to TOYOX Hose) that can securely connect the hose.

QDo you sell only the insulation part of the HYBRID TOYODROP Hose (HTD)?
A

We are sorry but we do not sell it.

QI would like to know the guideline for replacing the hose.
A

It depends on the usage environment and usage conditions (fluid, temperature, pressure, size, hose type, etc.). Check for deformation, hardening, discoloration, leakage, etc. by pre-start inspection and regular inspection, and replace or maintain if necessary. There is also a method to set the scheduled replacement date based on the initial replacement period and the past replacement frequency.

QI would like to know the replacement guideline for the dedicated couplings for TOYOX hoses (TOYOCONNECTOR FERRULE Type).
A

The TOYOCONNECTOR FERRULE Type coupling is not designed for regular disassembly cleaning.
When reusing TOYOCONNECTOR, replace the dedicated replacement sleeve with a new one. Also, please make sure to use a brand-new hose.
While the TOYOCONNECTOR FERRULE Type varies depending on the usage conditions, consider five disassemblies a rough guideline for replacing with a new coupling.

QI would like to know the guideline for replacing the KAMLOK.
A

If the cam arm of the KAMLOK COUPLER feels loose or the liquid oozes, it is an indication to replace the gasket. If the cam arm feels loose even after replacing the gasket, it is due to wear, so replace it with a new KAMLOK adapter.

QWhat are the differences between TOYOCONNECTORS and crimped products?
A

TOYOCONNECTORS adjust the length of the hose on-site
Fittings can be attached by tightening a cap nut with a wrench. (Check the type of TOYOCONNECTOR and which hoses are compatible)

Hose assemblies are specified by hose size, length, couplings, and are assembled by the manufacturer. (Check compatible hose and fitting types)

Both are dedicated fittings for TOYOX hoses.
*Crimping product fittings are not for individual sale.

QWhat is the maximum tightening torque in the safety band specification table? Is there data on the optimal torque when tightening the hose?
A

The maximum tightening torque in the band specification table is guaranteed by the manufacturer. Exceeding it may cause damage or the band tightening function to deteriorate. There is no proper torque value. There are many hose hardnesses, wall thicknesses and coupling types. Setting up is difficult as it depends on which part of the barb to be attached.

To solve such issues, we offer special couplings for tightening cap nuts called TOYOCONNECTOR that do not require torque management.

QDo you separately sell safety caps for safety bands? Can it be attached to the band edge of other companies’ hose bands?
A

Safety caps for safety bands are not sold separately. In addition, you cannot attach a safety cap to the tip of another manufacturer’s hose band.

In addition, do not use the product once the safety cap has been removed.

QAre the TOYOX hose bands compatible with RoHS2?
A

All hose bands are RoHS2 compatible. Certificates are available if necessary.

Necessary survey reports can be downloaded by registering as a member. Feel free to use them as needed.

QDoes the minimum bending radius refer to the length from the center point to the inside of the hose?
A

The minimum bending radius refers to the length from the center point to the center of the hose.

Does the minimum bending radius refer to the length from the center point to the inside of the hose?

QIt says that the TOYOSILICONE Hose is heat resistance. Is it fire resistance (flame retardant) as well?
A

No. It is neither fire resistance nor flame retardant.

QDo the hoses have specific service life? I want to manage the hose replacement schedule.
A

No service life is set for our hoses. Since many usage conditions such as fluid type, operating temperature, operating pressure, hose size and length are involved and the hoses are used in a wide variety of environments, it is not possible to set a specific service life.

Make arrangements based on the actual piping conditions at your company.

QAlthough a hose is is in use, it may bend or collapse in the middle, causing it stop or causing a change in flow rate. There are cases where work stoppages or loss occurs. Is there a hose that can improve this?
A

There are various types of hoses.
Hoses used in factories are roughly divided into hoses reinforced with thread and those reinforced with metal or resin coils.
If the currently used hose is reinforced with thread, the hose may bend or collapse.

It is possible to minimize bending and collapsing by using a hose reinforced with a metal or resin coil.
These reinforced hoses are resistant to bending and collapsing and can be used for vacuum applications.

In addition, there are hoses with a new structure that’s not reinforced with a metal or resin coil and is resistant against bending and collapsing.

QThe PVC hose currently used is not heat resistant and the hose often needs to be replaced. Are there hoses that last for a long time when using hot water of about 80℃?
A

If a normal PVC resin hose is used with food, hot water and cleaning agents at 60℃ or higher, the hose will harden, which may lead to problems such as leakage and disconnection of the hose coupling.

Depending on the pressure of food, hot water, etc., we offer hoses according to applications and usage conditions such as those that can be used up to 70℃ and 150℃.

Select a hose that meets the operating conditions.

QIs it possible to purchase hoses in shorter lengths than listed, and if so, is there a minimum length? Also, how does the pricing work for that?
A

Many of our dealers will cut hoses to the desired length. Please consult with your local dealer for available sizes and pricing.

QCan you provide product samples?
A

In order to provide products suitable for the usage conditions, etc., we provide samples upon confirming the usage conditions.

Note that samples may not be available depending on the conditions.

QHow should I cut a Toyox hose, and what tools will I need?
A

The cutting method will differ depending on the thickness and type of the hose.
We demonstrate some of the various methods and tools in our video “How to Cut a Toyox Hose.”

QThe hose has a bothersome odor. What type of hose should I use?
A

Select a low-odor hose that meets the operating conditions.

The hoses are available in PVC, polyolefin resin, silicone rubber and fluorine resin, and can be selected according to the odor level, intended use and conditions.

Difference in odor due to difference in hose materials (PDF)

QIs it possible to buy hoses in longer lengths than listed?
A

Yes, depending on lead times and quantities, we do our best to provide custom lengths. Please note that prices may differ. Consult with your local dealer for details.

QIs the hose softer as the minimum bending radius is smaller?
A

Smaller minimum bending radius doesn’t necessarily mean it is softer.

Although it is a measure of softness, it is not absolute. For example, the bend radius is TOYOSPRING < TOYORON, but in this case TOYORON feels softer. The softness varies depending on the thickness, material and reinforcement structure. Select an appropriate hose with reference to the deflection data and product samples.

QWhat is the reinforcement material used in the TOYOFOODS-S? Will it rust?
A

The reinforcing material of the TOYOFOODS-S Hose is made of hard iron wire that’s prone to rusting. Avoiding wetting the ends while using the hose.

Contact us for products that use a rust resistant reinforcing material.

QCan ground clips replace the hose bands? How are they installed?
A

Ground clips are not hose bands. Be sure to use hose bands.

Refer to the attachment for the installation method of the ground clip.

QDoes the TOYOCAP comply with the Food Sanitation Act?
A

Yes. It is made from polyethylene and is compliant with Japanese Food Sanitation Act Public Notice No. 201.

QAre there any products complying with the Food Sanitation Act?
A

There are several types of hoses complying with the Food Sanitation Act. Select a hose that meets the operating conditions.

In addition to the Food Sanitation Act, there are hoses suitable for FDA and other legal regulations.

QAre the TOYOX hoses compatible with RoHS2?
A

All hoses (standard products) are RoHS2 compatible. Survey reports are available if necessary.

Necessary survey reports can be downloaded by registering as a member. Feel free to use them as needed.

QCan highly concentrated ozone water be run through the TOYORON Hose?
A

Yes, that is fine.

QCan sodium hydroxide (caustic soda) be run through the TOYORON Hose?
A

We do not recommend doing so because that will lead to early degradation of the hose. After about a year of feeding sodium hydroxide, the hose will turn yellow and harden. After that, the hose will degrade further and become stiffer, and the inside of the hose will become brown. We therefore recommend using the ECORON or TOYOFUSSO Hose for more durability.

QCan sodium hypochlorite be used in the TOYORON Hose?
A

At room temperature, a concentration of up to 5% can be used. Even so, this will lead to premature aging as compared to water use. We therefore recommend using the ECORON or TOYOFUSSO instead.

QCan natural gas, liquefied petroleum (propane) gas and other flammable gases be run through Toyox soft PVC hoses?
A

Toyox hoses should not be used for flammable gases. Doing so may result in fires and extensive burning.

QCan gasoline be run through the TOYOFUSSO Hose?
A

Do not use fuel oil in the TOYOFUSSO Hose Series.

We do not produce hoses that can be used with fuel oil.

QCan sodium hydroxide (caustic soda) be run through the TOYOSILICONE Hose?
A

Solutions of sodium hydroxide (caustic soda) should generally not be run through the TOYOSILICONE Hose as it can cause degradation of the hose. For CIP (cleaning in place), however, a dilution of 2 to 3% may be used without problems. The TOYOSILICONE has even been used by a CIP equipment manufacturer. Even so, this will result in quicker degradation than using water or air.

QCan silicone oil be run through the TOYOSILICONE Hose?
A

This will not result in damage to the hose, though it may stick to the outside surface. We cannot, however, guarantee the TOYOSILICONE Hose for uses above 70℃.

QCan the TOYOSILICONE Hose handle conveying steam?
A

No, the TOYOSILICONE is not designed for steam.
The TOYOSILICONE Hose can handle up to 130℃ and 0.2 MPa of pressure, but this should be limited to short periods of time for sterilization purposes, and continuous use should be avoided.
In addition, temperature and other conditions vary depending on product, so be sure to check the precautionary material for details.

QIs there a hose that can be used for fuel oil?
A

We do not provide hoses that can be used with fuel oil such as gasoline, light oil and heavy oil.

QWhat is the guaranteed pressure for the TOYOCONNECTOR?
A

TOYOCONNECTOR Series is couplings dedicated for TOYOX Hoses. The warranty covers the operating pressure range of a compatible hose.
However, there are temperature conditions depending on the type of TOYOCONNECTOR. Also, the material’s resistance varies depending on the fluid, so check the coupling details, chemical resistance data, etc.

QAre there different-diameter types of TOYOCONNECTOR for reduced size?
A

There are no different-diameter couplings for TOYOCONNECTOR.

There should be a method of adjusting and installing using general different-diameter bushings or the like in the thread part.

QCan a TOYOCONNECTOR be attached and removed multiple times?
A

The TOYOCONNECTOR Series can be reused except for the all-resin type (TC3-PC).
Be sure to replace the sleeve (or rubber cap depending on the product) when reusing.
Also, note that it is not designed to be frequently attached or detached as in the case of disassembly cleaning.

QDo the HF, HM, HC and HNT coupling models come with gasket?
A

The HC model comes with a gasket, but the other couplings do not and must be provided for separately. Toyox does not sell gaskets separately.

TOYOX provides KAMLOK gaskets separately, but not other coupling packings.

QWhat is the difference between the male coupling and pipe thread coupling on the caulking bracket?
A

Male coupling is for sanitary use. It is not compatible with pipe thread.

QWhen using the Easy Connecting Joint with a HITRUN Hose, HR-6 and HR-8 have dedicated couplings, but what about HR-11 or HR-13?
A

Dedicated couplings are not available. Instead, use the following couplings. For the HITRUN Hose, use of common cap nut type couplings may cause the hose to come off or the inner piping to be cut. Be sure to use the Easy Connecting Joint that uses a hose band to tighten the barb nipple.
Example: Nitto Kohki 30SH/PH, 40SH/PH

QCan the TOYOCONNECTOR be used for other companies’ hoses?
A

TOYOCONNECTOR Series is couplings dedicated for TOYOX Hoses. Connectability with other companies’ hoses is not guaranteed.

Refer to the detailed page of the corresponding TOYOCONNECTOR for compatible hoses.* Compatible hoses and sizes vary depending on the TOYOCONNECTOR part number.

QCan you help me select the size of a barb nipple coupling for a hose?
A

For Toyox hoses, Toyox dedicated couplings are the best. If a genuine Toyox coupling is not provided , use a barb nipple available for purchase on the market. When selecting a barb nipple, ensure that it is appropriate for the size of the hose. It should not be used if it there is any damage or rust on the surface, and round the edges as much as possible before use.

QWhat order form and units are used for TOYOSILICONE Hose crimped products?
A

These are made-to-order products with delivery dates. Specify the coupling type, hose diameter, length and quantity when placing an order.

QAre the TOYOX couplings compatible with RoHS2? (Other than KAMLOK)
A

All couplings are compatible with RoHS2 except HIT fitting (with rotation fitting female spring). Survey reports are available if necessary.
Necessary survey reports can be downloaded by registering as a member. Feel free to use them as needed.

KAMLOK is available in types that connect to hoses, devices, equipment and piping materials.
Also, aluminum alloy, stainless steel, bronze and polypropylene (PP) types are available to meet various applications, fluids and usage conditions.

What kind of coupling is KAMLOK?

QI want to learn how to install the KAMLOK gasket. I’m trying to install a Teflon jacket gasket, but it’s tight on the side. Is it safe to push it in?
A

Forcibly inserting it may cause streaks and deformation in the Teflon part, which may cause leakage.
To install the gasket, immerse it in hot water at 80℃ for 10-15 seconds (increasing flexibility) and firmly insert the gasket diagonally along the streaks (including the filler part).
When purchasing a new product, gasket replacement can also be provided, so consult with the supplier.

QCan the gasket be replaced? Is it also possible to replace the gaskets specified at the time of purchase?
A

Gaskets are consumable items. They can be replaced by the customer.

It is also possible to replace with the gasket specified at the time of purchase. Specify when making order.

QDoes KAMLOK have couplings with different diameters to reduce the size?
A

KAMLOK does not have couplings with different diameters.

There should be a method of adjusting and installing using general different-diameter bushings or the like in the thread part.

QAre there any products such as lids to prevent foreign matter from entering into the KAMLOK couplings?
A

For each material, Dust Cap 634-B is available for couplers and Plug Cap 634-A for adapters.
However, they cannot be used in applications where pressure is applied or to prevent leakage. It is only for protection from dust and foreign matter.

QWhat is the difference between KAMLOK 633-C and 633-CT, 633-E and 633-ET?
A

The difference between KAMLOK 633-C and 633-CT is the difference in the outer diameter of the shank where the hose is inserted. 633-CT is narrower than the 633-C and is used to be inserted into hoses that do not easily expand, such as suction hoses in general.
If the size does not match, fluid leakage or coupling disconnection may occur. The same applies to 633-E and 633-ET.
Use 633-E or 633-C for our hoses.

QI want to mount the Dust Plug 634-A to the KAMLOK 633-DB-1/2. Do the 1/2 and 3/4 KAMLOK have the same fitting?
A

KAMLOK’s mating size is shared between 1/2 and 3/4 sizes. Therefore, the 1/2 and 3/4 sizes of the dust plug and dust cap are the same.

QIs KAMLOK adapter 633-AB-3/4 available with a different thread diameter of 1/2?
A

The KAMLOK adapter 633-AB-1/2 has internal thread diameter of 1/2.
Only KAMLOK 1/2 and 3/4 have the same fitting size, and available screw standards are 1/2 and 3/4.
*Except products made of PP

The same applies to 633-FB.

QIs KAMLOK available in NPT thread type?
A

We do not carry NPT thread type.
All products are PT thread type.

QI tried to insert a KAMLOK hose shank into a common suction hose, but it was difficult. Is there a good way to insert it?
A

There are methods such as warming the hose insertion part with warm water and applying soap water to the hose shank. Also, it is possible to change the 633-CT coupler and 633-ET adapter with a slightly narrower hose shank.

QIs it okay to connect two KAMLOK made of different materials? For example, is it safe to connect an aluminum KAMLOK with a stainless steel one?
A
