Regulations

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.

QAre certificates such as SDS and material certificate provided?
A

Certificates are made available for download by registering on our website.

In addition to SDS, material certificate, product specifications, Food Sanitation Act and FDA compliance certificate, we also offer catalog downloads and CAD drawing downloads.
Feel free to register.

*Some products may not be listed. In such case, feel free to contact us.

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.

Types / Full lineup

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.

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.

Function / Performance

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.

Connection

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.

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.

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

Specifications

QAre Toyox ferrule couplings ISO-compliant?
A

Yes. All are ISO2852 ferrule groove compatible parts. When connecting, use a packing for ISO ferrule couplings.

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.

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.

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.

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.

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.

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.
