Solved the problem of leakage from the CO2 cylinder. Had previously drained a 10 lb. tank in 1 day with wrong seal.

Works perfectly

Had to replace the seal in Taprite 742 regulator twice, leaking CO2. Thanks to Kegworks, was able to get the exact replacement.

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.

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.

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

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.
