Automatic Reverse-flow Prevention Coupling Socket for Acetylene, 3/8" Hose End

This automatic reverse-flow prevention coupling socket is designed for acetylene gas, featuring a 3/8" hose end connection. It installs on outlet pipes, hoses, and welding/cutting equipment to eliminate potential hazards during gas welding or cutting operations, simplifying equipment preparation and maintenance. The spring-loaded locking mechanism enables single-action connection and disconnection, minimizing hose damage and facilitating easy maintenance. Specifically engineered for fuel gas, it prevents incorrect connections.

Constructed with a brass body and steel plug, both chrome plated, this socket offers durability and corrosion resistance. It operates at a working pressure of 0.7 MPa (7 kgf/cm²) and a proof pressure of 1.0 MPa (10 kgf/cm²). The NBR seal ensures reliable performance across a temperature range of -20°C to +80°C. Ideal for marine and industrial welding applications.
