On some stems, the sensor could come in contact with the wheel as the stem is pulled with the sensor attached.Our policy lasts 30 days. The second method is to attach the sensor to the valve stem and then insert it into the wheel. ![]() The first method is installing the valve stem in the rim and then attaching the sensor. There are two installation methods depending on the type of snap-in valve stem you are installing. These valves have a longer cap than a non-TPMS valve stem.īehind the stem is a mounting point for a self-tapping screw that holds the sensor to the stem. The difference is that the molded rubber on the snap-in valve stem does not reach the threads and there is a tapered shoulder. Snap-in sensors can look like regular rubber valve stems. Sealing grommets are engineered to work at a specific torque. Leaks cannot be eliminated by tightening the nut more. Some TPMS service kits include the torque spec in the package. Don’t guess on the torque for the nut – look up the torque specifications for the vehicle you are servicing to make sure you use the correct figures. The typical torque values for the base nuts on a TPMS valve stem range from as low as 35 in.-lbs. The new nut may have coatings on the threads that prevent corrosion and leaks. The material of choice is typically aluminum. The nut is made of a softer metal than the stem, so it can be damaged or develop hairline cracks if it is over-tightened. If the seal is reused, it could cause a slow leak. The instant the nut is torqued, the seal/grommet starts to take on the shape of the surfaces it is sealing against. Grommets conform to the mating surface of the wheel. Mounting the sensor upside-down can cause relearn and transmission problems. The potted side of the sensor is to be positioned toward the wheel. When inserting the sensor through the wheel, keep pressure against the rear of the metal valve stem. This can change the torque values and cause you to snap the stem. Do not lubricate or use a sealant in this area. Pieces of the old seal can cause a slow leak. Clamp-on StemsĪnytime a clamp-on TPMS sensor is reused or replaced on a wheel, it is necessary to install new seals and valve stem nuts to ensure proper sealing around the sensor valve stem. No matter the type of stem, carelessness can result in a broken sensor or even a customer being stranded with a flat tire. ![]() For 99% of wheel and tire assemblies, the TPMS sensor is either a clamp-on metal valve or a snap-in rubber stem. ![]()
