Coupling Special Product Case Studies (Leakage Testing Edition)
Are you having trouble with airtight testing of complex work (pipes)? (Using hoses, hose bands, caps, etc.) Connect and disconnect with a one-touch coupling! ◆ We can manufacture special or custom couplings (fittings) from just one piece ◆ 【Production Examples】 □ Automotive manufacturer engine factory: Engine running tests Traditionally: Hoses were connected, hose bands tightened, and then disconnected after the test... Now: With the adoption of couplings, connections and disconnections can be done with one touch, significantly reducing labor. Moreover, using a rotary adapter allows for smooth hose handling! □ Leak testing of copper pipe piping for eco-cute systems Traditionally: Leak testing was done using negative pressure, with rubber gaskets being adhered for the test... Now: The testing method has changed to positive pressure, and with increased pressure, safe work can now be performed with couplings! □ Engine leak tests at construction machinery manufacturer engine factory Traditionally: A nut fixture was tightened onto M18 threaded work to seal it... Now: With two claws, the threaded section can be clamped with one touch, simultaneously sealing the end face!

basic information
Are you having trouble with airtight testing of complex work (pipes)? (Using hoses, hose bands, caps, etc...) Connect and disconnect easily with couplings! ◆ We can manufacture special and custom couplings from just one piece ◆ 【Production Examples】 □ Automotive manufacturer engine factory: Engine running tests Traditionally: Hoses were connected and hose bands tightened, and after the test, they were removed again... Now: With the adoption of couplings, connections and disconnections can be done with one touch, significantly reducing labor time. Moreover, by using a rotary adapter, hose handling has become smooth! □ Leak testing of copper pipe piping for eco-cute systems Traditionally: Leak testing was done using negative pressure, with rubber gaskets being adhered for testing... Now: The testing method has changed to pressurized, and since the pressure has increased, safe work can now be performed with couplings! □ Engine leak testing at construction machinery manufacturer engine factory Traditionally: A nut fixture was tightened onto M18 male-threaded work to seal it... Now: With two claws, the male-threaded screw theft area can be clamped with one touch, simultaneously sealing the end face!
