LPG connectors CGA510

ChrisJ

This may be a bit of a strange question but are all CGA510 connectors basically the same and interchangeable?

I see some connectors with a solid brass male connector and I see others with an O-ring. Some are called POL and others just CGA510 but best I can tell POL is CGA510.

What's the deal?

Can't answer that question, but the O-rings don't last very long on the type that uses O-rings to seal. I prefer the brass to brass connectors. I suspect them o-m ring type seal easier for HO's with less wrenching.
