Keep your hydraulic slide-outs moving reliably with this direct OEM-replacement manifold assembly from Lippert. The 256069 controls three slide-out rooms through the standard MIRC hydraulic system and is the correct valve manifold block when your existing unit is leaking, sticking, or failing to extend or retract a room. The mounting plate is not included -- order separately if yours is damaged or missing.
Lippert's MIRC (Motor In Ram Cylinder) hydraulic slide-out system is found on a wide range of towable and motorized RVs. The manifold and valve assembly is the hydraulic routing hub that directs fluid pressure to each slide room's ram cylinder, controlling extend and retract functions. When a valve fails -- whether due to internal contamination, seal wear, or physical damage -- all rooms controlled by that manifold can be affected.
The 256069 replaces the complete 3-room manifold and valve block as a single assembly, restoring proper hydraulic sequencing and pressure control to your slide system. Because it is a direct Lippert OEM part, it matches factory port sizing, solenoid valve configuration, and mounting footprint without modification.
Routes hydraulic pressure independently to three slide-out rooms, allowing each room to extend and retract under proper load without cross-interference.
Direct replacement part number for standard MIRC hydraulic slide-out systems -- no adapters, re-drilling, or modification required on compatible rigs.
Complete manifold and valve assembly weighs only 2 lbs., keeping system weight low and making handling during installation straightforward.
This assembly ships without the mounting plate. Reuse your existing plate if undamaged, or order the appropriate Lippert plate separately before beginning installation.
MIRC stands for Motor In Ram Cylinder -- a Lippert-engineered design where the hydraulic pump motor is integrated directly into the slide ram rather than being a remote unit. The manifold block routes fluid from the hydraulic reservoir to each ram, with solenoid valves opening and closing the correct circuit when you operate the in-coach switch panel. A failed or compromised manifold valve is a common cause of slow, incomplete, or non-responsive slide movement.
Replacing the manifold requires depressurizing the hydraulic system, removing hydraulic lines from each valve port, unbolting the assembly from the mounting plate, and reversing the process with the new unit. Label or photograph each hydraulic line before removal -- incorrect reconnection will cause rooms to extend when they should retract. Torque hydraulic fittings to spec and bleed air from the system after installation.
