Automatic Reverse-flow Prevention Coupling Plug for Oxygen, 1/4" Hose End

Enhance safety in your welding and cutting operations with this Automatic Reverse-flow Prevention Coupling Plug designed specifically for oxygen service. Installed at the outlet of pipes, hoses, or welding/cutting equipment, it eliminates the risk of reverse gas flow, preventing potential hazards. The spring-loaded locking mechanism allows for single-action connection and disconnection, minimizing hose damage and simplifying maintenance.

Crafted with a chrome-plated brass body and a chrome-plated steel plug, this coupling plug ensures durability and corrosion resistance. It features a working pressure of 0.7 MPa (7 kgf/cm²) and a proof pressure of 1.0 MPa (10 kgf/cm²), with an NBR seal suitable for temperatures from -20°C to +80°C. The 1/4" hose end size is standard for oxygen hoses, and the design prevents accidental mixing with other gas lines.
