Why this coupler
- Hansen 600 interchange — which means it couples with the widely used Hansen 600 oxygen coupler system.
- Oxygen service — which means it is intended for oxygen lines (at 100 psig or less) in welding and gas applications.
- Safety sleeve operation — which means the sleeve must be retracted to connect and disconnect, helping prevent accidental release.
- Solid brass construction — which means corrosion resistance and reliable gas-service performance.
Frequently asked questions
What is this used for?
Oxygen and compressed-gas service in welding, breathing equipment, shipyards, and construction. O60 interchanges with Hansen 600.
Is there a pressure limit for the gas?
Yes — O60 is intended for oxygen at 100 psig or less. Max coupler working pressure is 300 PSIG.
What does it interchange with?
Hansen 600 couplers. O60 (oxygen) and A70 (acetylene) use different connections so the two gases cannot be cross-connected.
Built for welding and gas-service lines. Pair this coupler with a matching O60 (Hansen 600) plug.
