It monitors air pressure in the system and signals the air dryer to purge when the correct cut-out pressure is reached, which helps keep moisture and contaminants out of your air tanks. You typically replace it when the compressor won’t build air properly, the dryer cycles erratically, or the governor leaks from its exhaust port. The part is an aftermarket replacement for the original Wabco unit and is commonly found on Freightliner and other commercial vehicles that use the 1200 Plus dryer.
