Western Enterprises Oxygen Check Valve 9/16-18 TPI Male/Female B Size 125 PSI

The Western Enterprises CGA-022 check valve prevents dangerous reverse gas flow in oxygen cutting and welding systems, featuring precision-machined brass construction with stainless steel internals for reliable operation up to 125 PSIG.

Engineered for B-size oxygen cylinders, this check valve installs directly at the regulator connection point using standard 9/16"-18 TPI right-hand threads. The machined brass body houses a stainless steel operating spring and valve disc that automatically closes when forward flow stops, preventing potentially hazardous backflow into oxygen supply lines.
