Automatic Reverse-flow Prevention Coupling Socket for Oxygen – M16 x P1.5 Female Thread

This automatic reverse-flow prevention coupling socket is designed for oxygen service, providing a safe and reliable connection between pressure gauges, hoses, and welding/cutting equipment. The spring-loaded locking mechanism allows quick one-action connection and disconnection, minimizing hose damage and simplifying maintenance. Specifically engineered for oxygen, it prevents incorrect gas connections and eliminates potential hazards in gas welding and cutting operations.

Constructed with a chrome-plated brass body and a chrome-plated steel plug, this socket offers excellent durability and corrosion resistance in marine environments. With a working pressure of 0.7 MPa (7 kgf/cm²) and a proof pressure of 1.0 MPa (10 kgf/cm²), it meets the rigorous demands of shipboard welding applications. The NBR seal ensures a tight, leak-free connection across a temperature range of -20°C to +80°C.
