Ball Lock Gas Disconnect - 1/4" OD Barb

I have about 15 of these and have not had one fail as of yet. You can not beat the price for the quality of these.

These QDs are more than adequate for average homebrewing use. I was a little disappointed in the build quality (plastic runoff on the seams, lower quality plastic than some of the QDs I have worked with in the past). All in all, if you need some decent quick disconnects and don't want to break the bank, these are a solid option. Just don't expect professional grade build quality and finish (they are, after all, listed as homebrew kegging supplies).

No problems, it work perfectly, I prefer this model beacause you just have to conect the tube directly on it, no screwings parts that can leak.

Had one disconnect fail after 4 months (leaking through the top). Could not get it to reseal. At $4.99 it a price that is hard to beat and it cheap enough to have a few spares around.

Works great! No problems or leaks yet.
