Simplify your tire maintenance and ensure precise inflation with the Haltec HE-373 straight truck valve extension. Engineered specifically for commercial trucks, RVs, trailers, and dual-wheel configurations, this lightweight extension threads directly onto standard valve stems to provide easy access to otherwise hard-to-reach inner dual wheels. Crafted from rugged, corrosion-resistant nickel-plated brass, it delivers maximum durability without adding unnecessary mass that can cause stem vibration and fatigue.

Key Features & Benefits

• Extended Reach: Features a 5-1/8" effective length to bring deep, hidden valve stems within easy reach of any standard inflator or pressure gauge.
• Lightweight Design: Minimizes total wheel mass to protect your existing valve stems from vibration-induced cracking and stress over long hauls.
• Double-Seal Technology: Equipped with a built-in double-seal mechanism that ensures a positive, leak-free connection the moment it's installed.
• Short Collar Fitting: Designed with a compact 3/8" short collar for a clean, secure fit on standard bore (.305"-32 thread) valve stems.
• Heavy-Duty Construction: Built from premium nickel-plated brass to withstand harsh road conditions, debris, and extreme weather.
