Your draft beer system can’t function properly without an intact CO2 tank regulator in place. Over time, Taprite CO2 regulator fittings can become worn at the seals and cause harmful CO2 leaks in your setup. This flat seal is the perfect CO2 tank leak stopper to prevent this issue from ruining the pressure in your draft beer system.
Simply use a 5/32” Allen wrench to remove the brass plug at the end of the stem, remove the old flat seal, replace with this new one, and then reinstall the plug. You’ll be enjoying cold beer again in no time.
If your Taprite keg regulator is showing signs of a CO2 leak, add this flat seal for better air flow.

fixed problem
fixed leak, co2 tank was useless without it

Perfect
Correct size, fixed the leak. Thanks!
Solved the problem of leakage from the CO2 cylinder. Had previously drained a 10 lb. tank in 1 day with wrong seal.
Arrived on time. The flat seal fit snug on the regulator.
Works perfectly
Had to replace the seal in Taprite 742 regulator twice, leaking CO2. Thanks to Kegworks, was able to get the exact replacement.
Worked great and solved the leaking CO2.
Great
Perfect fit
Perfect Fit
Seal was a perfect fit for my regulator. Took a little bit more time to get it but worth it when it arrived.
Worked well but be careful to get it centered as any off center will leak.
Fit perfectly stopped the air leak
Great price, fast delivery.
Good quality replacement seals.
Replaces the O-ring/washer on a Taprite regulator. It is held in place by a bolt in the center of it that unscrews with an Allen wrench. If your Taprite regulator starts leaking seemingly for no reason, check the O-ring/washer because it degrades over time.

Need more quality control
Seals too large to seat into place
Stopped leak
When I was connecting a refilled tank I could not get it to stop leaking. At first I thought it it was the tank. After looking at a parts diagram I decided to order the seal. The leak stopped. I kept the packaging slip in case it happens again. Thanks

Perfect fit. Resolved my leak.

Needed to replace mine as I was losing CO2...

Works
I damaged the previous seal and had been using the fiber washer the CO2 fill company provides and was losing all me co2 to a slow leak. This fixed it. Be careful not to over tighten the connection or you will damage the seal and have to buy another.

the washer doesnt fit!
I purchased 6 of these and had them shipped priority and when they arrived they didn't fit my Taprite regulator.

Ok
This worked well.
