Coupling Special Product Examples (Leakage Test 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 and custom couplings (fittings) from just one piece ◆ 【Production Examples】 □ Automotive manufacturer engine factory: Engine running tests Previously: Hoses were connected and hose bands tightened, then removed again after the test... Now: With the adoption of couplings, connection and disconnection 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 Previously: Leak testing was done using a negative pressure method, which involved adhering rubber gaskets for testing... Now: The testing method has changed to a pressurized system, and with increased pressure, safe work can now be performed using couplings! □ Engine leak tests at construction machinery manufacturer engine factory Previously: A nut fixture was tightened onto an M18 male thread workpiece to create a seal... Now: With two claws, the male thread's screw theft area can be clamped with one touch, simultaneously sealing the end face!
