Automatic Reverse-Flow Prevention Coupling Socket for Oxygen – 1/4" Hose End

This automatic reverse-flow prevention coupling socket is designed specifically for oxygen service, providing a safe and efficient connection for welding and cutting equipment on board. The socket features a spring-loaded locking mechanism that allows single-action connection and disconnection, minimizing hose wear and simplifying maintenance. Constructed with a chrome-plated brass body and steel plug, it ensures durability and corrosion resistance in marine environments.

Engineered to prevent reverse gas flow, this coupling eliminates potential hazards during gas welding and cutting operations. The 1/4" hose end size fits standard oxygen hoses, and the NBR seal ensures reliable performance across a wide temperature range. With a working pressure of 0.7 MPa (7 kgf/cm²) and proof pressure of 1.0 MPa (10 kgf/cm²), it meets the demands of professional shipboard use.
