Product Advantages
Dual-Purpose Design for Air & Liquid Filling
The TR-622A valve stem supports both air inflation and liquid ballast filling, giving service technicians and operators the flexibility needed for different tire setups. Liquid ballast is often used in agricultural tires to improve traction and vehicle stability.
90° Bend for Easy Access
The 90-degree angle provides improved access during inflation and maintenance, especially in tight wheel wells or deep rim applications. This ergonomic design makes the TR-622A easier to work with than straight valves in many heavy equipment configurations.
Standard Fitment for Common Equipment
With a .625″ (5/8″) valve hole fitment, this valve stem is compatible with most heavy-duty agricultural and road-grader rims, offering a universal replacement option for maintenance shops and distributors.
Durable and Corrosion-Resistant Construction
Built with quality metal materials, the TR-622A resists wear and corrosion from moisture, dirt, and chemicals in agricultural and construction environments, extending service life and ensuring reliable performance.
