Subject: [PSUBS-MAILIST] Low pressure
scuba output
Hello folks
I'm starting work on the air system for my wet sub ( don't have the
resources for a dry sub yet, but I wanted to start somewhere) and
have a quick question regarding the use of the low pressure output from a
standard scuba reg. I have a BCD connector to connect the reg set to the
air system and I'm looking at using standard copper pipe and solder ring
fittings (called yorkshire fittings here in the UK) to connect to the
valves. The question is, is the pressure out of the first stage constant
or effected by the external water pressure and what is this pressure, does it
vary from reg set to reg set?
From talking to the guys at work we believe the pressure rating
of the pipe and fittings is in the order of 10 bar and I seem to think
that the scuba gear low pressure air is of a similar order. Can I solder the
pipe or do I need to look at braising this pipework?
I noticed a number of the subs on the site use standard scuba reg
sets for low pressure air can anybody help me out on this
Regards
Simon
