Use these high quality, food-grade quick-disconnects on your gas and beer tubing lines. Uses might include the following:

* On a gas system to unhook your tank and regulator from your manifold so you take it with you.
* On a beer line to easily switch between ball lock, pin-lock, or a commercial tap
* On a counter-pressure bottle filler to be able to easily connect to your existing gas line.

This plastic quick disconnect set features 1/4" barb which can be used with tubing ID 3/16" through 5/16". 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 need not worry about them leaking gas. The internal valve spring is 316 type stainless steel and the o-ring is food grade buna-n.

Will the 1/4 barb work with any of the 8mm OD EVA barrier tubing?
Jerry Huang on Mar 24, 2022
Will this hold pressure on standard 5/16 gas tubing? Seems that with 1/4 barbs I'm going to have leakage.
RICHARD H STRAWTER on Dec 11, 2019
BEST ANSWER: I have at least 30 such connections in my keezer with no leakage problems. Use good quality and well-sized band clamps, or (much) better, Oetiker pinch clamps, which create a good seal and will save you lots of skinned knuckles.
Does this have a built in check flow valve to prevent backflow?
Michael Tangen on Aug 19, 2019
BEST ANSWER: The QD fittings have shutoff valves to prevent flow when disconnected but once they are connected they are open to flow in either direction. So, no, there is no check valve incorporated to prevent flow in both directions.
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.
Danny E on Sep 10, 2020
BEST ANSWER: I have used these with 5/16" tubing Ultra Barrier and otherwise. Worm-gear clamps are your best bet to cinch down the seal, but they do chew up the Ultra Barrier tubing pretty well, so if you ever take one out I recommend snipping off the end of the tubing that has been clamped before.
I notice no one seems to be utilizing these QD’s for vacuum wine racking and filtering. I normally utilize 1/4 inch hoses to vacuum rack. Are these not right for vacuum racking wine?
Richard Robinson on Dec 12, 2018
BEST ANSWER: Hi Richard - Yes these can be used for vacuum racking wine.

Quick Disconnect
I needed the quick disconnect to repair a 40 year old carpet shampoo machine due to lack of parts availability. It works perfect and is back into business. I bought two disconnects just in case I might need it again in the future. Oh and I had a beer after the repair. LOL

These are awesome for use on both gas and beer lines. I've had problems with gas-in poppets not sealing fully when the gas fitting is disconnected from the post, causing CO2 leakage from the keg; now I leave the gas fitting on the keg, with the other end of the gas tubing connected to the male part of this quick-connect fitting, which solves the leakage problem, and I can easily add gas (for serving or carbonating) any time I need. I also use them on beer lines with picnic taps.
