Steel Quick Connect Coupler Socket – SM Series – R 1/8 Male Thread

This steel quick connect coupler socket (female) from the SM series is designed for reliable fluid transfer in pneumatic, hydraulic, and vacuum systems. Featuring a R 1/8 male pipe thread, it provides secure connections in marine and industrial applications. The socket incorporates a floating ball valve that automatically shuts off flow when disconnected, preventing fluid or air leakage.

Constructed from durable steel, this coupler socket withstands working pressures up to 1.5 MPa (15 kgf/cm²) and pressure resistance up to 2.0 MPa (20 kgf/cm²). Its compact, one-handed operation allows for quick coupling and uncoupling, making it ideal for hose assemblies on ships and offshore platforms. Suitable for air and other compatible fluids.
