Steel Quick Connect Coupler Socket – SM Series – Male Thread R 3/4

This steel quick connect coupler socket (female) from the SM series features a male pipe thread R 3/4 and is designed for reliable fluid transfer in pneumatic systems. The universal coupling allows quick connection and disconnection at either end, making it ideal for marine, industrial, and hydraulic applications where efficiency and safety are paramount.

Constructed from durable steel, the socket incorporates a floating ball valve that automatically shuts off flow when disconnected, preventing air leaks and system contamination. With a working pressure of 1.5 MPa (15 kgf/cm²) and pressure resistance up to 2.0 MPa (20 kgf/cm²), this coupler is suitable for air service up to moderate pressures. The single-ball locking mechanism ensures a secure connection while maintaining ease of use.

Part of the SM series, this coupler socket is a direct replacement for IMPA code 351308 and is compatible with standard pneumatic tools and hoses. Its compact design and robust construction make it a dependable choice for ship chandlers and marine engineers.
