“If you’re searching for an economical CO2 regulator that still offers reliable performance and great durability, this Fermentap Dual Gauge CO2 Regulator is just the thing.

This CO2 regulator regulator features hand-adjustable pressure that doesn’t require any tools, as well as a built-in tank gasket so that you won’t have to change the tank without one. The 30 PSI low pressure gauge offers a more precise range for dispensing beer at home when compared to the standard 60 PSI gauge, and the built-in pressure relief valve blows off at 40 PSI for added safety. With its chrome-plated brass construction, this Fermentap Dual Gauge CO2 Regulator will offer years of rust-free, reliable use.”  [full description]
