2 Pair Ball Lock Keg Post, Stainless 304 Homebrew 19/32’’-18 Co2 Gas kegerator Beer Liquid Cornelius Corny Poppet Spring Spare Sealing O-ring Keg Posts Kit for Brewing Quick Disconnect Fitting

Nice replacement part, spring is MUCH stronger than the older smaller springs on corny kegs. Also, threads are the same on beer and gas, which they usually aren't on older kegs.If I have any doubt at all on older kegs, I just replace the whole fixture to be sure. Saves future headaches for a few bucks.

No issues with sealing lock tight. Just check your brand of corney keg before buying. I had one I had get retro pinlocks would tight on threads. That was my fault not the manufacturer.

If you have older kegs and no longer trust them holding pressure you should consider these. These things have brought all of my older "fleet" of kegs back in the mix. They are really easy to install and are really good quality.

These worked really well to resolve a problem I had with a damaged liquid post on a ball lock corny keg. The poppet was a slightly different design than my original keg posts, but I honestly like these better as the spring used is much stiffer.I did take off once star because I noticed there was some significant metal shavings/material inside one of the posts, which was likely left there as part of the thread cutting process. Once that material was removed, the post worked just fine. Definitely do a good inspection when you're cleaning the parts before initial use.

Got these really fast & some extra o-rings were included. Fantastic

*Update*I originally gave these a 1 star review for the reasons below. The seller quickly reached out and even though I had already returned these to Amazon for a prompt refund, he sent me a complementary new set. They were sent out very quickly through Amazon. He did not ask me to change my review, but I did. Original problems aside, the replacement set works well. They thread onto the keg smoothly and seal. The gas-in post now fits snugly with my gray quick connect and does not leak when I move it.--------------These looked nice, but that's about it. The gas out was tough to seal to the keg. I had to use a brand new tube oring (as I should), but before changing the oring, I tried another spare post with the old oring and that sealed fine. This did seal with the new oring, but it was worrisome that it leaked so badly with a good condition used oring. I moved on to test the gas in. That leaked big time on the seal with the quick connect. I changed the post oring. The leak got better, but still leaked with any movement. I did notice that the supplied orings are soft material, my spares are standard hardness. But I think the real problem is the depth of the oring groove. I didn't write down the measurements, but the groove is slightly deeper in these than my other gas posts preventing the oring from sealing tightly. This was also apparent in how easy the gas quick connect was to spin. Lots of up and down play and pretty much zero resistance to rotate the quick connect. It felt like there was no oring in there, not a tight fit at all. The flow through these posts was also very low. The gas was barely hissing through. Not recommended, too much time wasted testing them.

They looked like a good quality post, so I installed them right away.I was very happy to find that the posts fit perfectly and did not leak. I have been using them for a few months now and they have been working great.I am very happy with these keg posts.

Some reviewers had issues with the machining, but mine were perfect. No leaks, nicely threaded. These fit perfectly on ball lock corny kegs. The quick release gas/liquid fittings lock on and off of these posts much more smoothly than the posts that originally came with my keg.
