When used with the male QD these quick disconnect seal up very well in either flow direction, without a lot of work in connecting them. This will work with any of our H503 and H507 series of quick disconnects. However, it does not work in conjunction with any of our plastic or brass quick disconnects. These feature a 1/2" Male National Pipe Thread on the ends for easy connectivity to almost anything.

The quick disconnect will hold pressure for typical brewing applications when moving liquids at 60psi or less. 1/2" ID. Gasket temperature range is -40° to 250° F. Open port, does not have shut-off.

We 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 our Stainless QD fittings have a near unanimous 5 star review with retail customers.

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

How do I know if these disconnects will fit the ones I currently have that were not purchased from More Beer?
james stamey on Mar 23, 2020
BEST ANSWER: There is no way we can guarantee that these fittings will fit the ones you already have. While they are all practically the same and almost standard, some manufacturers are just different enough to have some leakage or problems locking/unlocking. All we can do is wish you good luck and hope they will work for you.
Was going to use this fitting to transfer from my fermenter to a Soda Keg that has a ball lock fitting. What quick disconnect fitting would I need to do this ?
Eric L. on Oct 16, 2018
BEST ANSWER: Hi Eric - As mentioned, this is a rather large ID for post fermentation racking.

So far all we can say is these babies do what they say, quick release. Makes life much easier for our 7 gal test system.

fits, doesn't leak
What can you say about a plumbing fitting? It fits as expected and doesn't leak. There are no moving parts on it.
