When a triple EIRC hydraulic slide-out system fails to extend or retract all three slides evenly, the flow divider block is often the culprit. The Lippert 134625 is the genuine OEM replacement block designed specifically for triple EIRC slide-out systems -- restoring balanced hydraulic flow and reliable slide operation without modifying your existing system.
The flow divider block in a triple EIRC hydraulic system is responsible for splitting pump output evenly across all three slide-out cylinders. When this block wears, develops internal leaks, or fails outright, you may notice slides that move at different speeds, fail to fully extend, or refuse to retract. Replacing the block with the correct Lippert 134625 unit eliminates those symptoms and brings the system back to factory specification.
This is a direct OEM replacement sourced from Lippert -- the manufacturer behind the majority of hydraulic slide-out systems found in fifth wheels and Class A motorhomes built over the past two decades. Using the correct part number ensures proper port sizing, internal metering, and fitment into the existing manifold block assembly.
Genuine Lippert part 134625 -- matches original port sizing and internal metering for triple EIRC systems without modification.
Designed specifically for three-slide EIRC hydraulic configurations, delivering equal flow to all three slide cylinders.
Machined hydraulic block construction at 3 lbs -- durable enough for the continuous pressure cycles of RV slide-out use.
Backed by Lippert's limited 1-year manufacturer warranty for defects in materials and workmanship.
EIRC stands for Electric-In, Ram-Controlled -- a Lippert hydraulic slide-out architecture that uses an electric motor-driven hydraulic pump to pressurize hydraulic rams that extend and retract slide rooms. Unlike cable or rack-and-pinion systems, EIRC systems rely entirely on hydraulic pressure balance. The flow divider block sits between the pump and the individual ram lines, metering output so each slide moves at the same rate and force.
In a triple EIRC setup, one pump feeds three separate slide circuits. A failed or worn divider block causes unequal pressure distribution -- often presenting as one slide moving faster than the others, or a slide that stalls partway through travel. Replacing the divider block is the correct corrective step once pump output and cylinder integrity have been confirmed.
Replacing the flow divider block requires depressurizing the hydraulic system fully before disconnecting any lines. Residual pressure in hydraulic circuits can cause fluid ejection and injury. The block mounts into the existing manifold assembly, and line connections are typically JIC or O-ring face seal (ORFS) fittings -- match your existing fittings before ordering adapters.
