air compressor fittings/hose for co2

Brewing Processes

Is there any reason I can not use fittings and hose from an air compressor for my CO2?  I have quick disconnects, fittings and hoses rated to 300 psi sitting around collecting dust…and the threads fit my co2 regulator and my gas manifold too…

Is there any compelling (or dangerous) reason not to?

They should work just fine. Some air compressors get some oil in the air, so I would use new fittings.

Yeah, I thought of that, but my compressor is not one of those, and the fittings I have sitting are either never used, or lightly used (like once).

Thanks Tom.
ps, you and I are neighbors (so to speak).

My experience is that the air ball fittings leak, even if just a tiny bit. Now, if my compressor cycles a little more, who cares. If you’re buying $20 bottles of CO2 every two instead of 6 weeks, that could become annoying. Personally, I wouldn’t do it.

I am using a quick disconnect, and that is the part I am watching for a leak.  My guess is that after a lot of use, it will start to leak…but, with teflon tape all connections seem to be holding.

Thanks for the input Oscar.
