CO2 Leak Stopper for CGA320 Valve

This leak stopper for CO2 cylinders screws directly into the standard carbon dioxide valve, creating a tight, secure seal between the regulator and valve. It is a permanent O-ring solution that eliminates the need to worry about changing seals, as it provides a reliable, leak-free connection. With no modifications required to the cylinder or regulator, this leak stopper is a simple and effective way to ensure your CO2 system remains secure and functioning properly, requiring only a 5/32" Allen Wrench for installation.
