We manufacture rubber packings, gaskets, O-rings, sealings, all made in Japan. Our products are mainly used for water-instruments, gas-instruments, for 69 years. We assist your development for R&D, make samples for your trial products, manufacture your mass products, all about rubber packings.
Now we are featuring about our study for Hydrogen-Resistance-Rubber, and introducing the progress. Hydrogen-Resistance-Rubber to be used in the hydrogen station, is currently being studied about EPDM rubber for -40°C (-40°F)& 90MPa, FKM rubber for 150°C (302°F)&90MPa. O-rings made of EPDM have been applied in emergency breakaway coupling used in H2 dispenser of 70MPa hydrogen station. O-rings made of FKM have been applied in H2 compressor of 70MPa hydrogen station.
