H220002- Meritor Tire Inflate System ThermALERT Screw

Genuine Meritor tire inflate system thermalert replacement screw part number H2200 02.

The Meritor Tire Inflation System distributes pressurized air to trailer tires to help regulate inflation levels. Air enters the system through a central supply and travels through internal passages toward each wheel end. As pressure changes occur, airflow adjusts to compensate and equalize tire pressure across the axle set. This process continues automatically while the trailer is in motion. The system operates through mechanical airflow rather than electronic control. Internal sealing components manage air direction without manual intervention. The Meritor H220002 functions as a press-plug style component within trailer tire inflation circuits.
