Stainless Steel Quick Connect Coupler Socket SH Series — IMPA 351221-351226

This SH series stainless steel quick connect coupler socket is a general-purpose female coupling used throughout shipboard air and water systems. Cargo ships, container vessels, tankers and offshore support vessels rely on these sockets at deck washdown stations, engine room air lines, workshop pneumatic tools and freshwater service points. The self-closing floating ball valve stops flow the moment the male plug is disconnected, so crews can change tools or hoses without shutting down the line or spilling water onto deck.

Machined in stainless steel for corrosion resistance in salt-laden atmospheres, the socket is rated for a working pressure of 1.5 MPa (15 kgf/cm²) with a pressure resistance of 2.0 MPa (20 kgf/cm²). It is intended for air and water service and uses a single shut-off ball-lock design — the most common and widely understood coupling type at sea. The full range covers 6 individually ordered variants under IMPA codes 351221 through 351226, so purchasing officers can match the exact hose and thread size required for each connection point.
