CUPLA for Hydrogen Use

Hydrogen CUPLA

For High
Pressure

HHV CUPLA

We developed the first coupling in Japan for supplying and fueling with high pressure hydrogen gas, HHV CUPLA.
Used in commercial hydrogen stations and various types of mobility.

HHV CUPLA 70 MPa

HHV CUPLA 35 MPa

Max. working pressure
87.5MPa

Receptacle/Simplified nozzleSpecial made-to-order

Max. working pressure 87.5 MPa.
Adaptable to air tightness tests and pressure resistance tests.

*Simplified nozzle is not equipped with a valve or filter.

For Low
Pressure

H2-CZL CUPLA/H2-ZEL CUPLA

Used for supplying hydrogen to the fuel cell device.

H2-CZL CUPLASemi-standard

Compact size saves space.
Unique valve structure reduces air ingress and gas release during connection and disconnection.

  • Small but high flow rate.
    Size 1/8: Outer diameter of 16 mm (Cv value 0.81)
    Size 1/4: Outer diameter of 18.5 mm (Cv value 1.62)
  • Easy operation, push-to-connect function.

H2-ZEL CUPLASemi-standard

Unique valve structure reduces air ingress and gas release during connection and disconnection.

  • Easy operation, push-to-connect function.
  • A variety of sizes have been standardized to support a wide range of applications and situations.
  • Automatic shut-off valves in both socket and plug prevent fluid spill out on disconnection.

For Medium
Pressure

H2-HSU CUPLA

Used for hydrogen transportation, filling for storage, and various testing applications.
Max. working pressure
21.0MPa

H2-HSU CUPLASpecial made-to-order

Separation prevention mechanism is easily locked by turning the sleeve after connection.

  • ●It is made of stainless steel, but achieves the same working pressure 21.0 MPa as steel.
  • ●Separation prevention mechanism prevents accidental disconnection.
  • ●Automatic shut-off valves in both socket and plug prevent fluid spill out on disconnection.

Make use of hydrogen easier.
Easy and quick CUPLA connection for hydrogen fueling / supply!
