Description 

This German made connector features a one way check valve, to allow gas into a keg, while preventing beer from seeping out. These release pressure at 3psi. For the gas side (usually marked IN) of a ball-lock equipped keg. This fitting is threaded, and fits our D03 and D21 Gas Connectors, as well as our D66 barbed adapter. 3" tall.

Note: These are precise factory fitted pressure valves, and should not be taken apart for cleaning (internal parts are not available as spares, and an assembly diagram is not available).

CMB GAS BALL LOCK FITTING WITH CHECK VALVE
Well built Connector. Keeps the beer out of my CO2 lines. Works great. Highly recommend.

Fantastic Product
I am beyond pleased with this ball lock check valve. It is high quality well built mechanizim. No liquid dares to get in your lines. I pressurized this valve up to 50psi (which I believe is beyond the manufactures suggested pressure) and it still worked incredibly well. The see through color is also pretty cool. Liquid does get into the valve cavity. I just make sure to clean it out by force carbonating warm water and then purging the valve with a pressurized line. wha la clean valve. Planning on buying 5 more.

gas check valve connector
So far they work as described and do a good job at keeping the beer from backing up into the gas line.  I have ten of them hooked up, and ordered 4 more for a friend after he saw mine when I reordered the last time.  The 3 psi may interfere with conditioning, and the beer seems to pour slowly, but time will tell.  It would be great if there was a way to adjust the psi in the valve.

High Quality Fitting
This is a high quality, well made fitting.  Compared to my other fittings, it seems to fit more easily on my kegs and feels more sturdy.  My other fittings (which I'll mention are NOT the brand William's sells) have never seemed as solid, and sometimes leak CO2 when not on a keg.  I appreciate that these seem better made and so far I've had no similar problems.

I don't know how well the check valve part works, but I'm glad to have it after a few previous (silly, preventable) mishaps.

These are pretty pricey. but they re high quality.  If the price doesn't scare you off or if you especially want the check valve, I highly recommend these.

Not recommended
I bought three of these. One very slowly let's co2 through and the other two don't let any co2 through. I put my standard disconnects on and they worked perfectly fine. I'm not sure what's going on, but I doubt I got three bad ones. Unfortunately, I'm pretty sure I'm past the return period, so I guess I need to eat the $45.

Will this let gas out of a keg and stop when any liquid starts to come out or will it not even let gas out? Thanks
This will prevent gas from escaping a keg. Keep in mind it has a limit of around 35 PSI, so it will not prevent high pressure beer (30 PSI or more) from leaking back into the lines.

Hi - do you sell a barb adapter to got to 3/16 tubing please?
We only have a 1/4" barbed adapter, it is part D66, and will fit this product. You can often dip 3/16" tubing in very hot water to soften it, and it will fit 1/4" barbs.

You might also check out our part L93, which is a 3/16" hose barb swivel elbow that fits this product.

What is meant by release pressure 3psi? You can't charge a keg to 10psi?
Release pressure means the pressure needed to activate the check valve so gas can flow into the keg.  You can certainly charge a keg to 10 PSI or higher.
