Keep your RV's hydraulic systems operating properly with this direct-replacement Hydac coil from Lippert. Engineered for Lippert landing gear assemblies, hydraulic slide-out systems, and Level Up towable leveling systems, the 176954 coil pairs specifically with cartridge valve part 177094. If your landing gear or slides have stopped responding or are cycling erratically, a failed solenoid coil is a common culprit -- and this is the correct OEM-spec replacement to get you level and road-ready again.
The 176954 is a Hydac-manufactured solenoid coil built to Lippert's specifications for use across several of their most common hydraulic component platforms. It uses a spade-style connector with exposed prongs, which mate directly to the wiring harness connectors found in factory-installed Lippert hydraulic systems -- no splicing or adapters required in most applications.
Solenoid coils are the electrical half of a cartridge valve assembly. When the coil receives 12V DC from the control board or switch, it creates a magnetic field that shifts the cartridge valve spool, directing hydraulic fluid to extend or retract your jacks, slides, or leveling actuators. A shorted, open, or corroded coil will prevent that valve from operating, even if the hydraulic pump and fluid level are both fine.
Exposed spade-style prongs plug directly into factory Lippert harness connectors -- no terminal crimping needed.
Rated for 12-volt DC systems, matching standard RV house and chassis battery voltage used by all Lippert hydraulic control boards.
Designed to pair with Lippert cartridge valve part 177094, ensuring correct magnetic gap and actuation force.
Weighs only 0.4 lbs. Low profile design fits within the tight clearances of typical Lippert hydraulic manifold assemblies.
Before ordering, confirm the coil is your failure point. A functioning 12V coil will show measurable resistance across its terminals (an open reading -- infinite resistance -- indicates a burned coil; a short to ground also indicates failure). You can also check for 12V DC at the coil terminals while activating the relevant function from the control panel. Voltage present but no movement points to the coil or cartridge valve. No voltage points upstream to the control board, fuse, or wiring.
This coil is designed specifically for use with Lippert cartridge valve part 177094. The coil and valve are sold separately. If your cartridge valve body is also damaged or worn, order both parts together to restore full function. Using a mismatched coil and valve can result in incomplete actuation or accelerated wear.
Coil replacement on a Lippert hydraulic manifold is a common DIY repair. Typical procedure involves depressurizing the hydraulic system, removing the lock nut or retaining ring that secures the coil to the cartridge valve body, sliding the old coil off, sliding the new coil on, and reinstalling the retaining hardware. Always torque retaining nuts to manufacturer specification to maintain proper magnetic gap. Reconnect the spade connector and test all functions before returning the rig to service.
Inspect coil connectors and wiring insulation annually. Moisture intrusion at the spade terminals is a leading cause of coil corrosion and premature failure in undercarriage-mounted hydraulic components. Apply dielectric grease to the spade terminals after installation to slow corrosion in exposed mounting locations.
This listing is for the solenoid coil only. The cartridge valve body (part 177094), hydraulic manifold, pump, and all other hydraulic components are sold separately. Verify your existing cartridge valve is part 177094 before ordering this coil.
