CMB BLC Ball Lock Home Brew Keg Tap Complete Set

I bought these off Amazon Marketplace from a vendor called "Draft Warehouse".I received two ball lock quick-disconnects (QD) with CMB markings - so I have no reason to doubt that they are genuine.** The product that I received matched the second of the two pictures in the product listing -- i.e. both QDs have 1/4" flare fittings, with 1/4" nuts to connect the attached barb fittings (5/16" for gas in, 3/16" for beer line.)They work fine and were shipped quickly.

I bought a few Corny kegs that require a ball-lock attachment like this one, while the rest of my Corny kegs were all pin lock. These are the two main forms of attachments to a Corny keg. I prefer the pin-lock myself, as I feel it gets a more solid connection. With that said, these ball-lock connections work well on my ball-lock Corny kegs.Note that these have a 3/16" hose connector. That means you you'll need a 3/16" hose, which is pretty obvious. I have managed (in a pinch) to connect a somewhat larger hose using some teflon tape (around the metal part of the connector) and a hose clamp. This worked pretty well.This product was not given to me as part of any promotion. This review is entirely the result of my own opinions and use of the product.

What I recieved was two CM Becker ball lock disconnects a gas in qd white and a gas out black qd, both were CM Becker the genuine article. Both were 1/4" flare connections with a swivel nut and a 5/16" barb included. My bev out line is 1/4 so 5/16" is perfect. Better than described buy with confidence. 08/04/2022

While the coupler set I received does not appear to be made by CMB as pictured, They seem to work well enough though - hopefully they stand up to the test of time.They came with everything I needed to fit in my 3/16" and 5/16" beer and gas lines respectively. Did not leak even before clamping them down. They fit snugly on the keg posts without issue. Note - I had some trouble getting them on initially, there is a ring around the bottom that needs to be lifted before they go in. There were no instructions in the package, and this was a little confusing the first time I used them.The MFL connectors are a nice touch, so I am able to disconnect the couplers for cleaning by simply unscrewing them rather than having to yank them out of the lines.

I'm not sure if they changed the product since other people reviewed it, but I did receive CMB branded ball lock disconnects, with the proper size fittings attached. I'm using these to carbonate water in corny kegs at 50 psi, and they work just as well as my "official" ones from pepsi, at less than 1/2 the cost. The main difference that I can tell from the official ones is that the pin in the middle is made of a hard transparent plastic (polycarbonate ?) instead of stainless steel.Before using these, you'll want to tighten up the nut connecting the flare fitting, mine was a bit loose and sprayed water everywhere until I tightened it.Just FYI, the seller I purchased them from was NY Brew Supply. Perhaps the other (negative) reviews purchased it from a different seller.

I am on my third ball lock in the last year and a half. They're cheap enough to replace, though. When first using these, the mechanism is a bit stiff and I suggest "breaking" them in by using the carbonator part that attaches to your bottle and pressing the lock down on it several times on a flat surface, (put a kitchen towel down on your countertop). This will help loosen it for regular usage.I carbonate 2-4 bottles a day and after several months you may notice some leaking sounds. The lock will develope a crack somewhere and not seal as well as it's supposed to. Time for a replacement. But as I said, they're cheap so buy a pair of them to have a spare.

These are not CMB brand as shown in the picture. I could not get the gas coupler to stop leaking. It would not seal on the post on the keg. My other two CMB brand gas couplers did not leak on the same keg so it is definitely this off brand coupler. I have not tried the liquid coupler. It may be ok. The price even with shipping is very good but I would not recommend buying these given my experience.

One reviewer stated that the ball locks he received were not CMB, which initially gave me pause. However, THE BALL LOCKS ARE CMB.
