    Tyson Boyer from Dill Air Controls discuses common rubber stems used in tire pressure monitoring systems, or TPMS.

    Tyson Boyer: Hi! I am Tyson Boyer with Dill Air Controls; today I'm going to talk about the more common replacement rubber valve stems for tire-pressure monitoring systems.

    As TPMS continues to evolve, rubber valve stems attached to the sensor are increasing in usage and variety. The valve stem must be replaced when the tire is removed from the wheel for service or during tire replacement. The rubber valve stem is similar to traditional rubber valves that were used before the introduction of TPMS. Now let's have a closer look at some of the rubber valve stems used on vehicles with tire-pressure monitoring systems and how to install them. The VS-90 used in OEM vehicle since the 2013 model year has a small key shaped metal insert protruding out of its base. This metal insert easily slides into the sensor body under the metal clip, this allows you to release and remove the stem. Simply pull the valve into the wheel hole and then attach the sensor; be sure the sensor is a snug fit with no play. No special tools are required when servicing this valve design. The VS-950 is the rubber stem used on common vehicles like Ford, GM, and Dodge. It attaches to the sensor body with a T10 screw that is installed to a torque of 12 inch pounds. You can use a tool such as the Dill 5415 tool to ensure the screw is installed to the correct torque. The VS-1010 attaches to the Hyundai Santa Fe sensor with a lock nut. The lock nut is then torqued to 12 inch pounds. A bit such as the Dill 5415-2 bit can be used to ensure proper torque is applied. The VS-65 is found on Dodge RAMS, RAM Duallys, and Jeep Cherokees. It looks similar to a VS-950; however, they are not interchangeable. Notice the square end on the VS-65 and the longer brass tail as opposed to the VS-950 on the right. The screw must be torqued to 12 inch pounds when fastened to the sensor. Again, the 5415 tool should be used during installation. Be aware that not all rubber stems are installed first then attached to the sensors; refer to the instructions provided with the valve stem. Be sure to use OEM validated TPMS Service Kits. Other options in the market may look the same, but they may not have the durability to function as expected.
