Steel Quick Connect Coupler Plug – PM Series – Male Thread R 3/4 Heavy Duty

This heavy-duty steel quick connect coupler plug (male) is part of the PM series, designed for reliable fluid transfer in pneumatic, hydraulic, and vacuum systems. The plug features a male thread R 3/4 and is built to withstand working pressures up to 1.5 MPa (15 kgf/cm²) with a pressure resistance of 2.0 MPa (20 kgf/cm²). Its robust construction ensures secure connections and easy disconnection, making it ideal for marine and industrial applications where quick coupling and uncoupling are required.

The plug is designed with a floating ball valve that automatically shuts off flow when disconnected, preventing fluid or air loss. The single-ball locking mechanism provides a positive lock, ensuring safety and efficiency. Suitable for air systems, this steel plug is a standard component for hose assemblies in ship chandler and ship supply contexts.
