Purchased the set in Nov2015 (2male + 1 Female). Female fitting leaked my 20lb CO2 tank dry a year later (Dec2016). Morebeer replaced it, but I was reluctant to use it again. Got over my fears and tried them again in March2018 and unfortunately the male fitting failed at the plastic connection point (not my tubing connections). For the money spent in lost CO2 I could have just purchased a new 5lb tank. Not worth the risk to try again. Good Luck! Check those O-rings!

I keg a lot of sodas, and these disconnects make life so much easier! I have over $200 invested in them, but they save hours of time and substitute convenience for frustration.

Face it, cleaning lines over barb connections sucks. Flares are much better, but still a pain, take a minute, and need a wrench. These unclip in an instant and are more sanitary to boot. I just topped off a keg with CO2, then popped the gas onto a carbonator, then pressurized another keg. It took longer to write it down than to change the gas lines. Seriously.

When I need to flush a line with a QD on it, I clip a mating one in and bypass the shutoff. Otherwise, they hold gas like a champ, with no loss of pressure. Can't recommend them highly enough.

I only use these connectors for CO2, and they are fast, easy and give a positive seal.

I use these for both gas and beer lines. Makes it really easy to swap out co2 tanks and beer kegs. I've been using for over 6 years and never had any problems!

The only downfall is when you try to use your setup with a friend that doesn't use these.

I have three c02 tanks and I use a combination of corny and commercial kegs. Having these connections on all of my manifold ins and outs and keg couplers makes changing and moving things around a breeze. I highly recommend these if you run a manifold and/or use different types of kegs and couplers.

Adding a utility line to your gas system makes life much easier. I use this to push beer & purge carboys and barrels. Makes life easy.

These work great when working with beer, and

I have these on my spare co2 bottle's gas line. I use it to filter beer, push beer out of carboy, push star san and beer from one keg to another. I also have a set on my beer line for bottling. This quick connect sure saves time.

I have ball lock and pin lock kegs. Using these QDs in both the beer and gas line lets me easily swap keg post fittings so that I can keep using both type of kegs.

Makes switching hoses easy. I use it on my CO2 tank

Great for gas line quick disconnects. I have a male on my CO2 tank side and female on the line to gas in connector of the keg. In fact I have many QD to the gas in to the keg

Also makes it easier when using Co2 to move beer from fermentor to the key. The fitting can also fit into the carboy orange hood to force beer from the racking can to the keg (no siphoning)

Make sure you have some spare on hand for those occasions.

Now I need more of these. Very convenient!

I have one of these on my four lines. I use this for swapping from a keg gas inlet to a bottling gun. Very easy to connect.

These tough little connects pass through gas and liquid and hold up to any pressure you are likely to use. I keep one female on my gas-out line, and one male on my fluid line (so I don't get the various fixtures confused). I have lots of little CO2 and beer-transfer fixtures made up with one of these barbs on one end and whatever (counter-pressure bottler, ball-lock fixture, etc) on the other.

Makes moving lines a lot easier. No leaks.

I love the quick disconnects. Go on very easily, have had no leaks (but perhaps I should credit the clamps?). With a handful of these, I now can take parts from my fridge kegging system and re-assemble them for taking kegs to-go. It also makes hose line spaghetti in the fridge much easier to un-do. No need to disconnect at the keg, just pop them off at the door.

Perfect with gas or fluid tubing where you need flexibility to swap the lines.
