Medium and low pressure, dual-path open-close quick coupling S.P. type

Medium and low pressure, dual path open/close quick coupling S.P type

This is a quick coupling with automatic valves on both the socket and plug, designed for dual-path opening and closing. 【Features】 ■ Since it is a dual-path opening and closing type, both the socket and plug achieve a complete seal the moment they are separated. ■ The passage opens simultaneously with the connection, and closes simultaneously with the separation, resulting in minimal fluid loss and air contamination. ■ There is a wide variety of materials available for the main body, and valves, packing, and O-rings should be used according to the type of fluid. ■ The valves of the socket and plug adhere instantly to the valve seat, stopping the flow of fluid. Therefore, there is no fluid leakage. ■ The valves of the socket and plug push against each other to open the passage, allowing fluid to flow. ■ The O-ring inside the socket seals completely, preventing any external leakage.

Coupling Special Product Case Studies (Leakage Testing Edition)

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!
