Pressure Systems International (PSI) is encouraging users of its Meritor Tire Inflation System (MTIS) to purchase its proprietary valve stem connection hoses as replacements in order to maintain the quality of the system. According to the company, the proprietary hose delivers 95 percent of available air to the tires, while aftermarket parts contribute less and could compromise the system. The proprietary hoses are marked with a yellow stripe and imprinted with the PSI name.

Pressure Systems International (PSI) is advising customers to purchase proprietary valve stem connection hoses as replacements for the Meritor Tire Inflation System (MTIS).

The reason, PSI said, is that a proprietary hose delivers 95% of available air pressure to the tires while aftermarket and will-fit parts can deliver much less. Less air flow can compromise the performance of the MTIS, sold through ArvinMeritor.

To make proprietary valves clearly identifiable, PSI has included a yellow stripe and imprinted the PSI name on the flexible valve stem connection hoses. The company has produced a video to demonstrate the differences air flow can have on the MTIS.
