Boss Fitting O Ring

[AndyFromCB]

I got tired of dealing with the frog eaters (Zodiak Aerospace) and their non existent customer service and their inability to answer simple questions. I found that HRD Aerospace has a PMA for all old Scott kevlar oxygen tanks. $1700 from them vs $2400 from frog eaters. Shipped door to door in 3 days. Same tank as all are made by SCI and probably cost $300 for other uses without that FAA part number attached. So now, I need my altitude compensating regulator overhauled. Actually, I don't because it works fine, but might as well. Turbine Rotables quoted me $640. I can live with that. I assume what's involved is pulling out an airgun, blowing out the dust and typing up an 8130. That's what it took to overhaul my density and pressure controllers (plus an o-ring), seriously.  So I asked them if a new boss fitting o-ring in included in the overhaul. The answer was, no, another $100. WTF? For a metal o-ring? Is there another source for that part? A 300 series stainless steel metal o-ring? Any ideas?

Had a suspicion we'd been here before; look at

I just had to replace this part when replacing the O2 bottle. The part number for the Boss fitting, which is a metal ring gasket, is 59776-01. Aviall was able to supply it for around $75.

I don't understand overhauling the regulator without reason. Especially if you think that basically nothing is done.

I didn't overhaul the regulator. The bottle was timed out and had to be changed. After re-install, the old boss fitting was not sealing properly.
