150 psi Pressure Release Valve for ARB Lockers. No matter what kind of air system you make or buy to run your ARBs you absolutely have to have an in-line pressure release (150 psi) to protect your ARB seals. In case of pressure surge this will save your ARB.
With this piece installed in your system, if pressure ever spikes or goes above 150 psi, the spring will compress and release any excess pressure. This is not a one-time-use component and should last years.
