PERMA-SEAL- Means no more washers!

Perma-Seal is an insert that is installed on all SOURCE^TM CO2 Tanks.  The Perma-Seal insert eliminates the need for washers to be used on regulators, so there is nothing to lose or replace. Perma-Seal is made of commercial quality brass with a high quality o-ring that will last the equivalent of 1000 washers. With SOURCE^TM  CO2 tanks there is no need to worry about where the washer is, the tank is always ready to accept the regulator wherever you are! Perm-Seal can be used on other CGA-320 CO2 valves as well!
