In stock, will ship on Tuesday, March 28

The integrated Duotight design means you can connect your beer and gas line directly, easily and reliably - no need for additional fittings or clamps. It is a robust and compact design that is incredibly easy to assemble and disassemble, making cleaning and sanitising easy.
 The small form factor allows for easy stacking of rubber top kegs (they are 1¾" tall). The new cap design ensures a pressure seal with just hand tightening and it can be completely taken apart for cleaning with no tools required in case it gets clogged.

This fitting can take pressures of over 100 PSI due to its overmolded poppet design which does not require an O ring that can blow out. Extremely chemical resistant due to its polykeytone resin body, and EPDM and PP/EPDM overmolded poppet. They are also engineered to have a higher flow than traditional ball lock fittings for quicker keg transfers.
Designed to suit 8mm Beer/Gas Line. Due to the integrated duotight fitting the line will simply push directly into this fitting.

For this ball lock disconnect we recommend:

Item Z91 EVABarrier 4mm ID x 8mm OD Line (for 5' or less beer line runs)

Item Z92 EVABarrier 5mm ID x 8mm ID Line (for gas lines or beer runs over 7')

I have not had a chance to put it on yet; but I am assuming this product is as good as all others I have purchased. Williams seems to have excellent products and the salespersons are a pleasure to do business with.

Not as good as the push-in adapter (Z93)

Review by Mitchell on 4/25/2022

I find that the tube doesn't fit as well in these (G50) as it does in the push-in adapters (Z93). The tube slides into the push-in adapter a few centimeters giving you a sense of confirmation that it has made a good seal. However, with G50 the hose barely inserts into the quick disconnect opening. I've had several occasions where liquid leaked out because, despite pressing hard, there was a poor seal. Removal of the tube from this QD is nearly impossible without the tube removal tool (B38), which is also different compared to the push-in adapter. Even when correctly depressing the locking collar on G50 the tubing becomes damaged when attempting to remove it. Long story short the push-in adapter (Z93) works better (seals better and is easier to remove the tubing when needed).
