TWINLOK Coupler
Lower the arms until they click to lock the connection.
Preventing the arms from loosening and the coupling from disconnecting ensures safer, more reliable connection and disconnection.

TOYOCONNECTOR Coupler
Toward zero fluid leakage and hose disconnection problems.
The MS (Multiple-Seal) structure compresses and securely holds the hose over a wide area, helping prevent fluid leakage and hose disconnection. No retightening is required.

step 03
Select the size (nominal diameter)
Check the nominal diameter in the equipment or piping specifications, drawings, markings, or other relevant information.

step 04
Select the material
- Aluminum alloy
- Stainless steel
- Resin (PP)
- Bronze
* When the body material is resin (PP), the operating temperature range is 0–60°C. For all other body materials, the operating temperature range is determined by the temperature rating of the gasket used.
step 05
Select by pressure
The values below are reference operating pressure ranges at 23°C when using a Buna-N (NBR) gasket.

Select a gasket
Standard Gasket
Buna-N (NBR)
The standard gasket is the Buna-N (NBR), with an operating temperature range of -10 to 100°C.
* Not compliant with Japan’s Food Sanitation Act.
Replacement Gasket List
Select a suitable replacement gasket if the required operating temperature is outside the -10 to 100°C range or if compliance with Japan’s Food Sanitation Act is required.

*1 When using a solid fluorine resin (PTFE) gasket, select a coupler, adapter, and gasket of the same size.
Example: Use a 1/2" solid fluorine resin (PTFE) gasket together with a 1/2" coupler and a 1/2" adapter.
*2 For couplers with a super fluororubber gasket used with saturated steam, the coupler should be used at an operating temperature of no more than 160°C and an operating pressure of no more than 0.6 MPa.
