Quick Release Valve 289714 Heavy-Duty Air Brake System Component
The Quick Release Valve 289714 is an essential component for heavy-duty truck and trailer air brake systems, engineered to expedite the release of air pressure from brake chambers and improve brake responsiveness. Built to meet OEM performance standards, this valve reduces brake lag time, especially on long wheelbase vehicles, enhancing safety and control under heavy load conditions.
Manufactured with high-strength aluminum alloy and precision internal components, the 289714 valve offers long-term reliability and corrosion resistance. It is a direct-fit replacement for commonly used air brake configurations in Class 7 and 8 trucks, trailers, and vocational vehicles.
