I have the Kobalt QUIET TECH 26-Gallon Single Stage Portable Electric Vertical Air Compressor. SO far good! No issues BBUUUUUT! I have owned a few compressors in my life, and eventually the BRASS CHECK VALVE Explodes out/off with age. With every other machine one could get a replacement part CHEAP and install it.

With this compressor apparently not only can you not find a replacement you can’t even find a listing for any replacement parts such as the BRASS CHECK VALVE. This part is not even named or given a part number in the manual. As far as Third party repair parts suppliers no one even list this model. I find this hard to believe…

NOW this has not happened to me YET! KNOCK WOOD! But it will eventually.

THESE are not my pictures but they were posted by a guy that made a BAD review on the LOWES Review comment area. This is the ONLY COMMENT I have found about this issue. Seems a $400 compressor is dead once a $1.50 part gives up the ghost! I am reconsidering my Future purchase of KOBALT TOOLS. I had a brad nailer die a few years back after little use.

Does anyone have a source for these replacement parts?

It looks like just a threaded brass plug. Not knowing the thread size or type because of no part diagram or number is quite annoying but I bet you could order a high pressure one from McMaster Carr and never worry about it again.

You can generic pop off or check valves from just about anywhere.

I’ve been around compressors for 20 years and never seen that part fail. What PSI do you run?

I will never go past 125-150. The machine is rated 150 psi. The part didn’t FAIL, it did as designed. The part is suppose to POP off if pressure gets real high and the Pressure relief valve fails. I have had two give up the ghost in the past 20 years. I always unplug my Compressors when not in use. the last time one of these popped out was during the night when not being used or on. I believe over time it just gave out. I found an replacement and screwed it back in.

Ok. Nothing I do requires that high of pressure. Mine is set on 100. Once in a while if I run a impact a lot I’ll bump it to 120 but it’s very rare. I’d say running at higher pressures wears them out faster. No clue on what to tell you other than I’m sure they source their parts somewhere instead of making them so it’s just a matter of finding them. In my area there is a little mom and pop plumbing store that also works on gas fireplaces and such. If you can find a small place like that they’ll probably be able to assist in finding a few spares for peace of mind.

I’ve personally had my Craftsman compressor over 20 years, usually at 150 PSI and never had a problem.

Did have one go out on am old industrial compressor at a professional shop i worked at where the compressor was on all day every day.

That said, its standard brass fittings. You can go to any home improvement store, ACE, plumbing supply, online, amazon etc and get these standard parts. I can however buy some, write Kobalt on the package in blue sharpie and resell them for the low price of $40

Have your say...
