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 Review: Great customer service! - *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 desertcart for a prompt refund, he sent me a complementary new set. They were sent out very quickly through desertcart. 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. ## Features - No Leaks and Powerful Keg Application Kit: MRbrew ball lock keg posts come with quality sealing gasket o-rings and are designed with standard thread size to prevent leaks on connection between beer keg and keg post. perfect for most cornelius keg, corny keg. suitable for beer, soda, and other beverages dispensing, enjoy your craft beer on the go or on travel! please note that this is not suitable for pin lock beer keg. - Universal Standard Thread Size for Connecting Ball Lock Keg Fittings: The 19/32-18 thread of ball lock keg gas liquid post kit is cut well, is compatible with most ball lock keg disconnects, ball lock keg post with etches is used on the “in” port of corny keg to connect gas ball lock disconnect, ball lock keg post without etches is used on the “out” port of cornelius keg to connect beer ball lock disconnect, allows more options of extra functions and possibilities for your kegging system! - Perfect Homebrew Kegging Replacement Kit: The ball keg gas liquid poppets posts need replacing much often during the brewing process, 2 pairs of gas beer ball lock keg posts include 2 ball lock gas posts, 2 ball lock liquid posts, 4 keg post springs, 4 keg post poppets, 8 keg post poppets sealing orings, 8 ball lock keg post gaskets, enough and complete brewing gadget parts will solve your replacement problem easily. - Durable High-End Stainless Keg Post, Your Long-Lasting Use Choice: MRbrew cornelius gas ball lock keg post poppet spring are made of stainless, no burr, which has bright surface and great oxidation resistance, is not easy to get rust, makes cleaning easy. kegerator sealing o-ring is made of quality silicone and rubber, we also provide replacement O-rings, healthy material will not bring any odors to you carbonation beer, MRbrew brewing tools makes your beer brewing more economy! - Wide Application: ball lock keg post springs features great elasticity force to help keg post connect to ball lock keg tightly and prevent leaking perfectly from the connection between beer keg and keg post during your brewing process. you can connect ball lock keg post kit to ball lock keg fittings to use for kegerator keg beer tap, mini keg co2 regulator, co2 gas tubing beer line, mini keg growler kit to dispense juice, kombucha and other various carbonation beverages. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B9Y112HV | | Best Sellers Rank | #37,826 in Kitchen & Dining ( See Top 100 in Kitchen & Dining ) #7 in Beer Brewing Kegs & Kegging | | Customer Reviews | 4.4 4.4 out of 5 stars (784) | | Date First Available | August 17, 2022 | | Item Weight | 3.34 ounces | | Item model number | MR-2-BLKP | | Manufacturer | MRbrew | | Package Dimensions | 6.02 x 3.15 x 0.71 inches | ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/71ItK6DUoFL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: It states that these can be used to convert a Firestone keg to ball and lock, but then states further down that they are not compatible? Clarify plz.** A: If you want to convert your firestone kegs ( pin lock) to ball lock you can do that. But if u have pinlock disconnects for your beer and co2 lines they wont be compatible with these poppets. **Q: I just recieved these and it would seem I got 2 liquid ones. My kegs are marked in and out will not having the gas one effect use?** A: The ball locks are colored gray (gas in) and black (liquid out). Each fit on their corresponding posts. You can force the gray on the “out” post but most likely get leaks, both air and liquid. They are slightly diff sizes and I would recommend not doing it. **Q: Can you replace hex 7/8 keg posts on a cornelius co. keg. the thread is the same, but some people say no. had anone tried, what was the problem?** A: Thank you for your question.These 2 posts bottom thread size is I.D 1/2'', it can't replace 7/8‘’ posts. **Q: These are type b keg posts, correct?** A: Thank you for your question.This is Cornelius Type Ball Lock Keg post. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very happy with these keg posts *by N***P on June 7, 2023* I bought these keg posts to replace the ones on my Cornelius kegs.

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. ## Frequently Bought Together - 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 - MRbrew Homebrew Gasket Set, 20 Pieces Corny Kegging Sealing O-Ring Replacement Beer Soda Washer Kit for Cornelius Keg Lid Ball Lock Keg Post Dip Tube with O-Ring Removal Tool - Semfeil Brew 304 stainless steel Cornelius Keg Lid New Replacement Corny Keg (Soda Keg) Lid with New O-ring for Cornelius or Firestone Kegs for homebrew beer kegging… --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/472300250-mrbrew-2-pair-ball-lock-keg-post-stainless-304-homebrew](https://www.desertcart.hr/products/472300250-mrbrew-2-pair-ball-lock-keg-post-stainless-304-homebrew) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-15*
