Replacement Plastic Washer for CO2 Tank Valve Regulator CGA320 - Set of 10

The most common place for co2 leaks is between the tank valve and regulator nut. Replace your worn or missing washer for a tight seal and no more lost co2!

Washer fits tightly inside most co2 stem nuts for easy install. Just pop it into place and reattach your regulator securely to the tank.
