[PSUBS-MAILIST] Purge Valve

[Rick Patton via Personal_Submersibles]

Alan,
My O2 tanks are outside and I have a O2 cleaned 1st stage to knock it down
to LP before coming into the sub so I bought a CGA 540 to go onto the
bottle and then a bleed fitting that goes to that like I think you are
looking for then a machined fitting with O ring like a scuba tank valve
that my 1st stage reg attaches to. Go to "thescubadiversstore.com" and then
type in the search bar 46335 and it will pull up a bleed part but the one I
have does not the have threaded port for a gauge. The guy was really great
to work with and good prices as well. This will get you started and when I
get to me shop, I'l look up the part number that doesn't have the gauge
port and get that to ya.
Rick
