Stainless Steel Quick Connect Coupler Plug – PM Series – Male Thread R 3/8

This universal quick connect coupler plug is designed for reliable fluid transfer in hydraulic, pneumatic, and vacuum systems aboard marine vessels. The male thread R 3/8 ensures a secure fit with standard marine hose couplings. Constructed from corrosion-resistant stainless steel, it withstands harsh saltwater environments.

The plug features a floating ball valve on the fluid side that automatically shuts off flow when disconnected, preventing spills and pressure loss. The single-ball locking mechanism provides easy connection and disconnection while maintaining a leak-free seal under working pressures up to 1.5 MPa (15 kgf/cm²). Ideal for air and water applications in shipboard maintenance, deck operations, and engine rooms.
