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

This Automatic Reverse-flow Prevention Coupling Socket is designed for acetylene service, featuring an M16 x P1.5 female thread connection. It installs between pressure gauges, hoses, and welding/cutting equipment outlets to eliminate backflow risks during gas welding and cutting operations. The spring-loaded locking mechanism allows single-action connect/disconnect, minimizing hose damage and simplifying maintenance. The socket is color-coded and keyed for acetylene to prevent cross-connection with other gases.

Constructed with a chrome-plated brass body and a chrome-plated steel plug, this coupling socket offers durability and corrosion resistance in marine and industrial environments. Rated for a working pressure of 0.7 MPa (7 kgf/cm²) with a proof pressure of 1.0 MPa (10 kgf/cm²), it operates reliably across a temperature range of -20°C to +80°C. The NBR seal ensures leak-free performance with acetylene.
