Default Keg Pressure Tester

After going through two co2 tanks and thinking I fixed the leak both times I got sick of wasting co2 so I made a gadget to pressurize kegs with my air compressor. I got a $20 tire filler that used a 1/4" id hose and cut the filler hose off so I could put a barbed mfl connector on it. I threaded that to an mfl disconnect and it connects to an empty keg so I can put pressure in it and then spray some star San around the fittings.

Can anyone think of a reason this is a bad idea? I'm not using it to add pressure to beer, just empty kegs since it would obviously oxidize the beer.

That sounds like a great idea, certainly save on the c02. If you used to pump your beer up it would probably stale faster due to 02, but for just testing seals I like it! I've had the best luck putting a star san mixture into a little spray bottle and just hitting the whole top of the keg to find a leak. I have also once put it in the tub on one where I thought there was a leak, turned out that the leak must have been in my manifold or hose, the keg was fine.

Just a note that might help. I've had kegs leak at 5psi, but once they go to 10, they are sealed. I've also had a keg leak only on the air in poppet, so when it's hooked up it's fine. But if I take the keg out of the fridge and leave it the whole thing goes flat.

Good luck!

Smart way to test the kegs. Don't see a down side unless oil gets in there.

Make sure you are using an oil-less air compressor, otherwise you would be blowing oil into your keg.

I have a moister trap on the outlet of the compressor. Will oil make it through that?

My understanding is some oil will get through. It's not much but I wouldn't risk it.

I made something similar, and also use it to push sanitizer through the lines. instead of a compressor hookup, I used a valve stem from a bicycle innertube. It connects to my bike pump, and I can use it to test kegs, pressurize them to transfer fluid, or whatever else I can think of.

put a pressure regulator and relief valve on there, your compressor can easily exceed the safe limits of a keg.

Excellent ideas there. I might do the same.

Reynolds, the kegs have a pressure relief valve built in. Also, I'm only setting the compressor to about 40psi, nowhere near the max working pressure the keg is rated to. The tire filler also has a gauge built in and I haven't gone over 30 psi. I don't see much danger since I force carb beer at 30psi.
