I have a Central Pneumatic 2HP 8 Gal compressor (40400) about 2 or 3 years old. I use it only about once a month for a few minutes at most.
It just blew what is described as the “check valve” in the manual. Part of it that actually looks like the head of a bolt actually broke and shot off.
I called the 1-800 and they said that the part was not available.
I have looked a bit online, but can’t even see where I can buy another one. It looks like a very simple device. My guess is it is a pressure release safety valve that blows if the pressure is too high. I don’t think that is the issue. I think it was more that the part was a bit weak, but if I get a replacement I will check the pressure and make sure.
Anybody have an idea on getting a replacement?

Hey Nathan… you talk about the check valve, but then, it sounds like you may be talking about the PRV valve?
Either should be available and they need not be necessarily the same brand.
How about another post with a photo showing what it is you are looking for? Actually, upload a couple, one showing where the device was on the compressor, and another a close up of the broken device.
Check Valve for 40400
This site claims they carry parts for 40400, I have not find any negative reviews about them.

Thanks for the reply and the offer of help.
I looked at the newer model from Harbor Freight with the same HP and tank size and the part looked the same. When I got it it did have the opposite male/female threads, but I can find a fitting to fix that.
The problem I ran into was removing the old part. It shattered. as I tried to remove the mail part stuck in the female threads on the tank.
I broke one tool made to extract pipe in this situation. When I got another one I ended up denting the tank just pounding the tool in to place.
At that time I figured I had done enough damage and I had better cut my losses.
Thanks anyway.
