Tells you the pressure to the keg so you can adjust accordingly for the type of beer you are drinking. Nonadjustable “shut down” blows off at 55-65 psi. Has an air shut off switch.
The polycarbonate bonnet is lighter weight and stronger than zinc bonnet regulators and it will not corrode in wet environments. No special tools are required to raise or lower the CO2 pressure. The cap knob simply pulls out so it can be turned to adjust pressure up or down then pushes back in to lock in pressure.
