Regulator question

[trooper1954]

Hi, just inherited an oxy-actylene kit that was disassembled. My question is does this regulator require an o ring around the channel near the connecting nut? If so, is it a generic one or do I go to a welding store?
Thanks.

usually CGA-*** connectors does not require any o-rings ... at least the ones in the USA. Just make sure the mating surfaces are clean and does not have any debris. For oxygen make sure NO Oil..


The different CGA-*** connectors are used for different gases, there is a chart some where. yours says CGA-320.

As far as gauges... get one for your gas.

I think it is a CGA 520. A CGA 320 is for CO2 and uses a gasket.
