quick connect for O2 hose to solenoid

PCDiver · 7th September 2006, 07:08

I was wondering whether anybody was using a quick connect for the hose that goes to the solenoid. A quick connect would make it easier to take the head out of the frame/case.

Peter,

Steven just shipped a bunch of parts for me as I am planning to do either or both:

in-line shut-off valve to isolate solenoid jammed open.
QC on O2 feed hose.

Definitely will implement the shut-off valve, but still thinking about the benefit-risk of QC on O2 feed to solenoid.

Unless I could place it in such a manner that I could reconnect u/w if accidentally disconnect, I might skip it.

Still thinking...

I'm not too worried about reconnecting. I would not reconnect under water since that would bring salt water into the solenoid. I'd rather fly the unit manually. I'm more worried about the QC getting disconnected and either of the connections stuck in an open position. That would either cause water entry (solenoid) or deplete your O2 supply. DrMike mentioned this problem about the GCS system in another thread.

I had a Swagelok QC 4 with shutoffs laying around and did just that. It was a female 1/4" NPT. I just used a tap and rethreaded it to fit (also made an O-ring recess on the lathe) . If I was going to do it again, I'd use a QC6. The flow rate on the QC4 is marginal at times.

Did you read the thread in forum incident about quick disconnect quickly disconnected

?
Hope that coul help
