Co2 Leak Stopper O-Ring With Allen Key

The Co2 Leak Stopper O-Ring with Allen Key is inserted into the end of your Co2 tank, replacing the regulator washer permanently. If your Co2 tank does not have both MPT and FPT threads where the regulator connects then this part is not for you.

This stopper comes with a 5/32" Allen Key, negating the need for additional tools. When installing the leak stopper do not tighten too much in order not to break it.

Please ensure this product will work with your CO2 tank before ordering.
