The Bartec USA TPMS Mechanical Tool Kit, No. MT104 protects the TPMS sensor by changing the wear items. The Rubber Manufacturer’s Association recommends changing the grommet, valve core, retaining nut and dust cap every time the tire is removed from the wheel. This regular maintenance prevents leaks and failures, and limits corrosion. The kit includes tools to quickly and effectively remove, service and install TPMS sensors and the wear components.
