Review: Two different barbs and nuts - These aren't CMBecker disconnects, but they're inexpensive and work fine. They have a somewhat built in washer, so you can sometimes get away without a nylon flare washer, but I still prefer to place some on gas fittings. There are a few reviews regarding nut and barb sizes. These disconnects come as pairs, a gas and a beverage. Each pair comes with two barbs, and two nuts. One barb is 1/4", for 3/16" ID beverage line. It has a corresponding size nut, with a hole sized for it's barb, and 1/4" female flare connection. The other barb is 5/16", for 5/16" ID gas line, with a larger hole on the nut, and the same 1/4" female flare connection. The barbs are not interchangeable between the nuts, even though they will both fit in each one. All of the disconnects will fit in any of the nuts, but a 1/4 barb in the 5/16 nut may not seal well without a nylon flare washer, because the nut is designed for the larger barb. If you're making a jumper you'll need to make sure you're using the right size barb for your line, and will have to take the barbs from two different packages, as each set has one 1/4" barb and one 5/16" barb packaged together. They can be difficult to attach to the ball lock posts, some keg lube can help with that. If you're getting leaks at the flare connection, and are sure the barbs and nuts are paired correctly, or don't want to remove them to check, try a nylon flare washer. Really should have some around when dealing with this type of equipment anyway.
Review: Perfect item, no leaks works as advertised - What you need for Corny Kegs. I use them with an adapter to connect to a Sankey tap from Micromatic, that way I can go commercial with the Sankey, and if someone brings by their newest brew in a Corny Keg I can swap in seconds. Color coded. Grey for GAS, Black for BEER. Even in the dimly lit recesses of my buddies Kegerator, I can tell the difference no problem.

*by P***8 on March 25, 2019*

These work well. It would be nice to have a couple of each fitting size in case your regulator is not of the size that matches this setup. The quality is very good.
