Steel Quick Connect Coupler Plug – PM Series, R 1/2 Male Thread

This steel quick connect coupler plug (male) from the PM series is a universal coupling component designed for reliable fluid and air transfer in marine, hydraulic, pneumatic, and vacuum systems. Featuring a male pipe thread of R 1/2, it allows quick and easy connection and disconnection. The plug is compatible with corresponding PM series sockets and incorporates a floating ball valve on the fluid side that automatically shuts off flow when disconnected, preventing spills and pressure loss.

Constructed from durable steel, this coupler plug offers a working pressure of 1.5 MPa (15 kgf/cm²) and a pressure resistance of 2.0 MPa (20 kgf/cm²), making it suitable for compressed air and other non-corrosive fluids. Its compact and robust design ensures a secure, leak-free connection in demanding shipboard environments. Ideal for ship chandlers and marine engineers seeking reliable hose coupling solutions.
