This is a QR-1C style quick release valve for air brake systems. It rapidly vents air at the valve to shorten brake release lag, which improves response and driver control. The valve includes an integral double check valve, and is typically mounted near brake chambers on heavy-duty trucks and trailers. It is a common replacement part when the original valve sticks, leaks, or causes slow brake release.
Fits many tractor and trailer air brake systems using QR-1C style valves. Exact model years not verified; verify port sizes and crack pressure against OEM requirements.
