Secondary regulators do not connect to the CO2 tank, they have wall mounting brackets and are designed to connect inline to your primary regulator by a flexible low pressure gas line. This enables fine tuning of four different pressures at the same time. This allows you to have 4 different levels of carbonation in 4 different beers at the same time. Includes 0-60 PSI gauges, high performance 5/16" barb check valves, and and adjustable control knobs.
