Leak Stopper for CO2 Cylinders

The CO2 leak stopper screws into a standard carbon dioxide cylinder valve, between the regulator and valve, to create a tight, secure seal. The only tool you need is a 5/32″ Allen Wrench and a CO2 cylinder you don’t want to be worried about having to change the seals on because this is your permanent solution.
