[PSUBS-MAILIST] Parker Pressure Regulator

[Alec Smyth via Personal_Submersibles]

I believe I have the same one as Cliff. I'm going to look into swapping it
out for a SCUBA second stage, which I think will be both more sensitive and
definitely able to handle a larger off-gasing volume. What I'm wondering
about is how to connect something that's intended for a human mouth to
Swagelok tubing instead. Any suggestions are welcome!

Thanks,
Alec
