MRbrew 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

I bought these keg posts to replace the ones on my Cornelius kegs. The old posts were starting to leak, so I thought I would give these a try. The posts arrived quickly and were well-packaged. 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. They are a great value for the price and I would definitely recommend them to anyone looking for a replacement keg post. Here are some of the pros and cons of the MRbrew Cornelius Type Ball Lock Keg Posts: Pros: Affordable Easy to install Durable No leaks Cons: None

*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.

Purchased these to upgrade 2 pin-lock kegs to ball-lock. Delivery was quick, installation was easy, however one set worked great but the other would not seal the keg. Looks like they would not screw down far enough to make the seal. Had to put the pin-locks back on that keg which seal fine.

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.

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.

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.

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.

I’m not sure why there are so many positive reviews for these keg posts but the gas post leaks constantly. The parts seemed to be machined well but the gas post was leaking when I connected the gas line (with/without keg lube) and it emptied my 2/3 full co2 tank because of this gas post. I initially noticed it leaked and could wiggle the gas quick disconnect until the hissing stopped but it apparently was still leaking and emptied the tank over a day. I used a corny keg and connected multiple different gas lines to the keg post but they all leaked while they worked perfectly fine on my other kegs as normal so the issue is 100% with these posts. If you read the other 1 star reviews this seems to be a very common issue, so definitely don’t buy these posts or anything from this manufacturer.
