DESCRIPTION:
Model: Bendix LP-3 Low Pressure Indicator
Vehicles: Commercial trucks and trailers using compatible air brake low-pressure warning circuits
• Indicator Type: Pneumatically actuated low-pressure electrical switch
• Pneumatic Port: One 1/4" NPT
• Electrical Connection: One terminal
• Cut-Out Pressure: 60 PSI ± 6 PSI
• Actuation Range: 54-66 PSI
• Circuit Rating: 12 VDC, 10 A
• Actuation: Spring-loaded diaphragm and piston mechanism
• Construction: Die-cast metal body with nylon top cap
• Mounting: Direct threaded-port installation
• Function: Closes the warning circuit when air pressure drops below the specified threshold
• System Use: Activates a compatible low-air warning light, buzzer, or indicator circuit
Applications:
Designed for commercial truck and trailer air brake systems requiring a single-terminal low-pressure warning indicator. It is typically replaced when the warning light or buzzer does not activate during low pressure, remains active at normal pressure, operates at the wrong pressure, or the switch develops an air or electrical fault.

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 drain air-system pressure before removing or installing the indicator.
✔ Apply pneumatic-grade thread sealant to the 1/4" NPT connection without allowing sealant to enter the indicator.
✔ Connect the single electrical terminal according to the vehicle warning-circuit schematic.
✔ Tighten using the metal hex body and do not overtighten or apply force to the nylon cap.
✔ Pressurize the system and verify warning-circuit activation within the specified 54-66 PSI range without air leakage.
