Steel Quick Connect Coupler Plug – PM Series, R 1/8 Male Thread

This steel quick connect coupler plug (PM series) features a compact, push-to-connect design for rapid coupling and uncoupling in pneumatic systems. The male thread R 1/8 allows direct installation into air tools, hoses, or manifolds. When disconnected, the shut-off valve on the socket side automatically stops airflow, preventing leaks and enhancing safety.

Constructed from durable steel, this plug withstands working pressures up to 1.5 MPa (15 kgf/cm²) with a maximum pressure resistance of 2.0 MPa (20 kgf/cm²). Ideal for marine, industrial, and workshop applications requiring reliable air line connections. The single-ball locking mechanism ensures secure engagement and easy one-hand operation.
