To upgrade your brew system, and make your life easier, thread these QD’s on your kettle, mash-tun, pump and chiller! When used with the male QD, they seal up very well in either flow direction. They will save you time and prevent messes. Just get several silicone hoses of various lengths and put barbed male fittings on either end. Then use them wherever you need to in your system! They are so much easier to use than pushing and pulling the hoses off of barbs. It makes things interchangeable for cleaning, and provides quick installation and removal.

MoreBeer! designed the original stainless QD's for the brewing industry over 10 years ago. The same manufacturer has been machining them for us ever since. The design has certainly been copied but not with consistent quality. That is why MoreBeer! Stainless QD fittings have a near unanimous 5 star review.

Please Note: This product will NOT work with our Brass or Plastic Quick Disconnects.

This will work with any of our H503 and H507 series of quick disconnects. These feature a 1/2" Male National Pipe Thread on the end for easy connectivity to almost anything. The quick disconnect will hold pressure for typical brewing applications when moving liquids at 60 psi or less. 1/2" ID. Gasket temperature range is -40° to 250° F. Open port, does not have shut-off.

Can these be used for low pressure CO2 and O2? e.g., for carbonation stone in conical
Cynthia D. on Oct 19, 2019
BEST ANSWER: Yes, there is no chemical compatibility issues for stainless or seal and once engaged the orifice is more than enough for that application. The real question is what pressure rating does the fitting have compared to your gas supply max and what safety setting do you have on vessels. This fitting is likely 10+ Times higher rated then any carbonation pressure. O2 addition should be at less than 1-2 psig.

Things to be aware of, if using pure or high concentrations of oxygen, it is highly flammable and can easily auto ignite at high pressure and velocity. If you diffuse O2 in sealed keg, you could be making a bomb! If you stir a little in there is no issue. I stir via sintered metal rod in open top for the most part, but for my continuous units I meter the O2 in via tee fitting as it flows by.

Side note, seals are likely neoprene so they are good for high ethanol content. Some other vendors use buna rubber and they are not compatible with alcohols.
Can anyone kindly advise whether or not these female QD's are free-flowing at all times? (i.e. if I have a hose fitted with one of these on each end, will the liquid be trapped? or be able to escape?)

Good seal, good performance
I was a little worried because there was just a bit more… slop? in the fitting between this and the Male QD, but the flex at the joint did not translate to any leakage at all and this made by 3 pc FPT ball valve super mobile. I’ve only brewed using it once but I’m happy with it so far.

Works great, good quality
I converted my homebrew setup to make all transfer hose connections between HLT, kettle, pumps, mash tun, RIMS tube, etc. quick disconnect rather than barbed fittings. Much faster. These fittings (and similar tri-clamp versions) make everying quick and easy. These are very good quality.

Don’t forget male piece
Unless you have existing QD connections, this piece will not suffice on its own. You need the male piece to connect to. This is a quality product that make brew day easier.

Worth the money
Adding QDs can be expensive, but in the long run it is definitely worth it. These QDs are manufactured very well. I have purchased from other stores, but the quality is not the same. The whole unit feels solid and clean.

fits, no leaks
What can you say about a plumbing fitting? It fits, it doesn't leak, it has an o-ring in it that is probably replaceable if it ever wears out.

Great quick disconnects
I use these Male and Female QDs throughout my brewery - Female on all the hoses, and Male on kettles, pumps, heat exchanger, and wort chiller. No leakage whatsoever. They're expensive, but a joy to use.
