Frequently Asked Questions (FAQs)
What is the TR423 and when is it the right choice?
The TR423 is an extra-short rubber snap-in valve stem for tubeless tires with a 0.453-inch valve hole. Its compact profile is the right call for low-offset wheels, flush-mount wheel designs, and applications where minimal stem protrusion is needed to avoid contact with brake calipers, wheel covers, or center caps.
How does the TR423 differ from the TR413?
Both fit the same 0.453-inch valve hole, but the TR423 has a significantly shorter overall length. Use the TR423 when stem clearance above the rim is limited. Use the TR413 for standard wheel profiles where length is not a constraint.
What is the TR423 made of?
EPDM synthetic rubber body conforming to SAE J1205/J1206 standards, with a chrome-plated brass Schrader core pre-installed. EPDM resists ozone, UV, and temperature extremes better than natural rubber.
Can the TR423 be used on TPMS-equipped wheels?
No. TPMS sensors require a dedicated TPMS valve stem. The TR423 is for non-TPMS tubeless wheels only.
How often should valve stems be replaced?
OEM guidelines recommend replacing rubber valve stems every time new tires are mounted. Rubber degrades from ozone exposure, heat cycling, and age, which can cause slow leaks even when the tire itself is fine.
