The Haltec HE-394 is a premium, lightweight straight tire valve extension engineered specifically for commercial trucks, buses, and fleet vehicles. Measuring 8 inches in effective length, this extension solves the common challenge of servicing hard-to-reach inner dual wheels and deep-set rims. It provides a straight, rigid extension from the original valve stem, allowing technicians and drivers to quickly check tire pressure and inflate tires without removing outer wheels or struggling with awkward angles.
