A cross-reference listing means this part may be a suitable replacement for the listed part numbers. Always verify fitment before installation.
IMPORTANT INSTALLATION NOTES:
✔ Fully depressurize the air brake system before removing or installing the valve.
✔ Confirm one 1/2" supply/reservoir port, one 3/8" control port, and two 3/8" delivery ports.
✔ Verify the application requires an old-style valve with a nominal 4.0 PSI crack pressure.
✔ Install using the correct 6002 or 6006 mounting nipple and apply air-system-compatible thread sealant sparingly.
✔ Pressurize the system and verify balanced brake application, release response, and no air leakage.
