Brass Quick Connect Coupler Plug – 1/2" Hose End (PH Series)

This brass quick connect coupler plug (male) from the PH series is designed for 1/2" hose ends, providing a reliable and efficient connection for air and water systems aboard marine vessels. The plug features a floating ball valve that automatically shuts off flow when disconnected, preventing spills and maintaining system integrity. Ideal for pneumatic tools, water lines, and general fluid transfer applications in shipboard environments.

Constructed from solid brass, this coupler plug offers excellent corrosion resistance and durability in marine conditions. With a working pressure of 1.0 MPa (10 kgf/cm²) and pressure resistance of 1.5 MPa (15 kgf/cm²), it ensures safe operation under typical shipboard pressures. The single-ball locking mechanism provides a secure connection, while the push-to-connect design allows for quick and easy coupling and uncoupling without tools.
