Compact short rubber snap-in valve stem for TPMS sensor bodies that use a screw-in stem. Ideal when you need a low-profile look and extra clearance for tight wheel designs. Fits standard 11.3 mm (0.453″) rim holes and accepts a standard 0.305″-32 valve cap. Short profile (24 mm exposed height) for tight spoke/center designs. 11.3 mm (0.453) snap-in base for passenger/light-duty wheels. Brass stem core & post for reliable sealing and signal path. Ozone-resistant rubber resists cracking and weathering. TPMS-ready : mates with common screw-retained TPMS sensor bodies. Standard 0.305-32 cap/core thread (cap not included unless noted). (1) Short snap-in TPMS valve stem assembly. (1) Stem-to-sensor screw (as shown). Wheels with 11.3 mm (0.453) valve holes. TPMS sensors that use a screw-retained snap-in rubber stem (hex-seat style as pictured). Not for: metal clamp-in/high-pressure stems, 8.3 mm (0.327) motorcycle stems, or Presta valves. Exposed height: 24 mm (from rim surface). Rim hole size: 11.3 mm (0.453). Cap/Core thread: 0.305-32. Materials: Brass insert, durable rubber body. Lubricate the base and snap the stem squarely into the rim using a valve-puller. Attach to the sensor and tighten the stem screw to the sensor maker’s spec (typically in-lb range). Inflate and leak-check with soapy water. Tighten cores lightly (2-4 in-lb). Replace stems whenever sensors are serviced to ensure long-term sealing. Periodically check caps and cores for debris and proper seating.
