I'm currently taking care of some issues that caused me to lose most of a new 5 lb tank of CO2. One issue I found was compression damaged flat o-rings inside my ball lock gas in connectors. Once I unscrewed the back to remove the spring valve, there is a flat o-ring around the plastic threaded part. This is the source of the leak in my gas in ball lock connector.
I went ahead and bought a new gas in connector at my LHBS today for ~$6, but when I asked if they sell the replacement flat o-rings, they said you can't get them. Does anyone know a suitable replacement? I tried a "#14" round o-ring that I got from Lowe's, but with the faulty gas-in, it did not seal it up. I didn't try it on the new connector though.
Does anyone have a solution to sourcing these parts? I'm going to look at McMaster Carr to see what I can find.
The dimensions I measured for the new flat o-ring were:
14 mm O.D.
11 mm I.D.
1.7 mm width
1.3 mm height.
(I know the math doesn't work out exactly for these dimensions, but if you've ever tried to measure an o-ring with calipers, you'd know how hard it is.)
Thanks!
