Let the pressure off your kegs the easy way! This is a 1/4" FFL adjustable pressure relief valve that can be attached to the 1/4" fitting on a gas disconnect. It features an adjustable nozzle that you can use to regulate the rate at which gas is released from the closed system. This model also has a pressure gauge that reads from 0-60 PSI, so you know what pressures you are dealing with! These reliefs come in especially handy when transferring or filtering between kegs. As pressure builds in the receiving keg, the rate of transfer slows to a halt. Having pressure relief will allow the transer to continue unabated. Also usefull when jumping cleaner and sanitizer between kegs!
