Pricey but Oh So Worth It
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.

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

Great quick connects
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!

Couldn't live without them
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.

Very convenient
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.

Quick conn
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.

Solves ball vs pin lock problem
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.

Cannot recommend enough - makes life easier
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.
