Quick Connect Coupler PM Series 600 PM – R 3/4 Brass Thread

This PM series quick connect coupler (part no. 600 PM) is a single shut-off, externally threaded plug designed for efficient fluid transfer in pneumatic, hydraulic, and vacuum systems. Constructed from durable brass, it features a floating ball valve that automatically seals the flow path upon disconnection, preventing fluid loss and system contamination. The compact and lightweight design enables simple one-handed operation, making it ideal for marine applications where quick hose changes are frequent.

Rated for a working pressure of 1.0 MPa (10 kgf/cm²) and a proof pressure of 1.5 MPa (15 kgf/cm²), this coupler is compatible with air and water. The R 3/4 thread ensures a secure connection with standard BSP taper fittings. Suitable for deck washdowns, pneumatic tools, and general shipboard fluid handling.
