It threads into the spindle plug of the wheel end using a 1/4 inch NPT connection. The stator directs air flow into the tire’s inflation system, while the integrated filter helps keep the air supply clean. This part is typically replaced during routine maintenance of the MTIS system or when the system is not maintaining proper tire pressure due to a clogged filter or worn stator.
