Warning WARNING: Oxygen increases combustibility. Fire and explosion could occur causing severe bodily injury or death. Be sure to select the proper coupling for your application and use it only within the specified service pressure range.

Pressure ratings are for socket and plugs with threaded end connections. Pressure ratings of couplings with hose stems may be significantly lower and will depend on the type of hose and the method of clamping
