Sherpa Big Air Compressor Repair

We’ve been using a Sherpa Big Air Compressor infrequently for about a year. Initially we were delighted with it’s performance after we re-wired the unit for our application. A month ago, it’s performance seemed to decline and it completely failed two days ago.

The immediate cause of the failure was that a thin-walled brass tube between fittings connecting the cylinder head / tank / air fittings broke.

The longer term issue is a design flaw (in my opinion) where the only support for the tank and air fittings is this thin walled tubing. As the compressor runs, the tank & fittings vibrate a lot. That vibration seems to stress the tubing & I think leads to the failure. I hope to fabricate some additional support for the tank & remove the problem.

Anyway, while I have a request in to Sherpa’s technical support my previous experience there suggests a quicker resolution could come from finding the parts myself. I’m wondering if anyone recognizes these pieces (the check valve components fell out when the tube failed) and could suggest a United States based source? The threads are metric pipe. Here’s another image:

Thanks for any suggestions.

Thanks for the suggestion. I should have mentioned that I tried McMaster Carr before posting - no luck.
