Replacement washer fits between a Taprite regulator and the CO2 cylinder. Reusable.

Over time, Taprite CO2 regulator fittings can become worn at the seals and cause harmful CO2 leaks in your setup. This flat seal is used to repair and replace those old, worn seals and restore your beer-dispensing system to its prime.

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.

Dimensions are:

3/32" thick
7/16" ID
5/8" OD

Works great

These seemed to be out of stock everywhere for a while so I was down to only one CO2 tank. Found them here, easy install, no leaks anymore. Thank you!

After losing my second tank of co2 due to a very slow leak at the tank coupler I went searching for the proper o-ring for my Taprite regulator Assm. Note each brand uses a different type o-ring. This was the correct ring for the Taprite brand!

Bit touchy

This will work with the Taprite CO2 stem, it just takes some tinkering to get it to fit. First step is to remove the center retainer with a hex wrench. Remove the old seal and press the new one in as best you can. It probably will not seat well at all at this point. Next, put the retainer back on and tighten with the hex wrench, then remove it again, then re-tighten. This seated the seal for me. I tested and it's holding pressure like it should.
