Savvy homebrewers love quick disconnects on their gas lines! They give you the ability to quickly move hoses from one configuration to another with ease!
These quick disconnects feature 1/4" barbed fittings which can be used with 3/16", 1/4" or 5/16" line. The quick disconnect functionality is activated by a shrouded thumb latch. The temperature range is -40F to 180F. They can handle a vacuum to 120 psi - so you don’t need to worry about them leaking gas. The internal valve spring is 316 type stainless steel and the o-ring is food grade Buna-N.
In short, these QDs are durable, user friendly and versatile. A no-brainer!

For the male side, see our H550A, or buy both sides together as a set.

Has anyone used these with the Ultra Barrier 5/16" gas tubing? The description states that 5/16" line will work, but I've read conflicting accounts online. I haven't seen anything specifically mentioning the Ultra Barrier in use with these quick connects.

great quality and value
I bought this to couple with the CONP775 CO2 adapter. Very pleased with the build quality and solid grip/purchase. Holds pressure perfectly and doesnt break the bank!

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

One of the best ways to manage your CO2 or any gas line
Makes a snap of rapid disconnection from CO2 or O2 with yeast wand. Always have some extra on hand.

I note that many wineries use the same for their Argon

Very useful for CO2
I don't use these for liquid but find them great for CO2. When I keg it's easy to connect a line to flush out the air. If I was doing it again I'd take a look at the Kent style, but these work fine.
