110500P
The 110500P is a spring brake priority valve for heavy‑duty truck and trailer air brake systems. Its job is to supply air first to release the spring brakes before building reservoir pressure, which prevents compounding and protects the system. You replace it when the valve fails to hold pressure correctly, causes slow brake release, or no longer meets FMVSS 121 compliance. This aftermarket valve directly replaces Haldex 110500, Bendix K025778, Sealco 110500, and many other OEM numbers.
Designed for common heavy‑duty trailer air brake setups. Verify your reservoir size and port threads (3/8 NPT supply, control, delivery; 1/2 NPT reservoir) match the valve before ordering. Interchanges with many OEM part numbers—check your existing valve’s part number against the cross‑reference list.
