A great deal on a high quality dual gauge CO2 regulator. Check out these features:
Hand adjustable pressure - no wishing you had a screwdriver in your pocket to change pressures.
30 PSI low pressure gauge - A more precise range for dispensing beer at home (as opposed to the standard 60 psi gauge)
Built in tank gasket - so you are not stuck making a tank change without a gasket.
Built in pressure relief valve - that is set to blow off at 40 psi for safety. Also features a pull ring so you can release excess pressure at any time, a very handy feature.
On/Off valve with barb- easily connect line and turn off supply of CO2 for working with keg connections etc.
Chrome plated brass - so will not rust.
Large CO2 diaphragm - for increased performance and reliability.
