Ensure effortless inflation and pressure checks on your heavy-duty wheels with the Haltec HE-393 Valve Extension. Specifically engineered for commercial trucks, buses, and RVs, this 6-inch straight extension solves the hassle of reaching deeply recessed or inner dual tire valves through wheel hand-holes.

Key Features & Benefits

• Extended Reach: Features an effective 6-inch length to bring hard-to-reach inner dual inner stems out to a manageable position.
• 1" Long Collar: Designed to thread securely onto the existing valve stem, providing excellent structural stability and minimizing thread exposure.
• Lightweight Metal Construction: Built with high-grade, lightweight materials to minimize centrifugal weight on the valve stem assembly, reducing the risk of premature stem failure.
• Positive Air Seal: Equipped with a precision double-seal mechanism that prevents air loss, ensuring reliable pressure maintenance.
• Universal Compatibility: Standard .305"-32 cap thread fits standard large and small bore tire valve stems. Works seamlessly with both tube-type and tubeless assemblies.

Target Applications

• Commercial trucks, tractor-trailers, buses, and motorhomes.
• Perfect for inner dual wheel hand-hole access.
• Recommended for use with rubber wheel stabilizers (e.g., Haltec H-2225 series) to eliminate road vibration and stem whipping.
