This is a pressure relief (safety) valve for heavy-duty truck air systems.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It is calibrated to open at 150 PSI to prevent over-pressurization damage to air dryers, tanks, and other components. It is commonly used as a direct replacement for the valve on WABCO System Saver 1200 and 1800 air dryers, but fits other air systems with a compatible port. Replace the valve if it leaks, fails to pop at the correct pressure, or constantly vents air.
