CO2 Leak Stopper
The brass C02 leak stopper is a permanent fitting. It screws into the end of the C02 tank and replaces the regulator washer.
This part replaces the built in seal on the regulator stem. Please check to be sure this is the right part for your tank and regulator.
If your tank does not have both MPT and FPT threads where the regulator connects then this part is not for you.
Requires a 5/32" allen wrench to install it.
