Description
Product Overview
The WAYASDCU straight truck valve stem is engineered to meet the exact specifications of the original equipment OE number TR574. Crafted from solid brass, the stem offers superior strength, corrosion resistance, and a lightweight profile that enhances overall tire performance. With a 19mm base diameter and a long, compact stem, it is optimized for tubeless tire applications, delivering a secure seal and consistent air pressure retention. Each unit weighs 1.98 pounds and ships in a compact package measuring 7.09 x 4.49 x 1.89 inches, making storage and handling straightforward.
Usage
Designed for a wide range of heavy‑duty trucks, these valve stems excel in both commercial fleet environments and individual owner‑operator scenarios. Whether you are navigating long hauls across highways, operating construction equipment on rugged sites, or simply maintaining a daily delivery vehicle, the brass construction resists wear from road salt, moisture, and temperature fluctuations. The universal 0.625‑inch inner diameter ensures compatibility with most truck tire valve holes, though we recommend confirming your tire’s valve hole size before purchase. Installation requires no special tools—simply thread the stem into the valve hole, tighten securely, and you are ready to roll.

FAQ
What trucks are compatible with this valve stem?
The stem is compatible with most heavy‑duty trucks that use a 0.625‑inch valve hole diameter. It is ideal for commercial fleets, construction vehicles, and long‑haul trucks. Always verify your tire’s valve hole size before ordering.
