| Intended Application | - Compatible with pneumatic brake and air supply systems in heavy-duty commercial vehicles equipped with compatible air compressors. It is installed either by direct mounting to the compressor (using the appropriate gasket) or remotely on the chassis to automatically control system pressure. Its primary function is to regulate air pressure between maximum (cut-out) and minimum (cut-in) values by acting on the compressor's discharge mechanism.
- Always compare with your OEM part number prior to purchase to confirm full compatibility.
