A cross-reference listing means this part may be a compatible replacement for these part numbers based on OEM or distributor data.
IMPORTANT INSTALLATION NOTES:
✔ Mount valve with ports oriented per OEM routing; confirm 1.25" hole spacing
✔ Verify preset pressure before installation if application requires alternate PSI setting
✔ No delivery check valve – install only where reverse pressure is not present
✔ Do not overtighten; use thread sealant rated for pneumatic fittings
✔ No re-torque required post-installation – factory torques are final
