When replacing the valve stem connection hoses on the Meritor Tire Inflation System (MTIS) by PSI, it is recommended that the proprietary MTIS hose be used to maximize the performance of the system.
When replacing the valve stem connection hoses on the Meritor Tire Inflation System (MTIS) by PSI, it is recommended that the proprietary MTIS hose be used to maximize the performance of the system.
The PSI hose delivers 95% of available air pressure to the tires. The amount of air carried to the tire is critical to the performance of MTIS. Keeping a maximum flow of air from the automatic inflation system to the tires ensures that the recommended air pressure set by the fleet is maintained during operation.
Pressure Systems International has added clearly identifiable markings to the flexible valve stem connection hoses of the MTIS by PSI, including a yellow stripe and the PSI name so they can be clearly recognized.
