Product details:

This beer regulator is a necessary part for any draft system. Its polycarbonate bonnet and brass design makes it durable and easy to use. This double gauge keg regulator has one gauge that tells you the pressure to the keg and another that shows the amount of remaining CO2 in theair tank. Its nonadjustable "shut down" blows off at 55-65 psi. It has a convenient CO2 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.
