Keep your multi-room hydraulic slide-out system running smoothly with the Lippert 173475 replacement manifold. Designed specifically for RVs equipped with multi-room hydraulic slide-out setups, this 8-bank manifold distributes hydraulic flow evenly across multiple circuits, ensuring each slide room extends and retracts with consistent, balanced force. A direct OEM-style replacement means no improvising -- just reliable, like-for-like performance.
Managing more than one hydraulic slide room introduces a real challenge: uneven flow can cause one slide to move faster or with more force than another, putting stress on seals, rams, and the slide mechanism itself. The Lippert 173475 solves this with an integrated flow divider built directly into the 8-bank manifold body, splitting and metering hydraulic fluid across all circuits simultaneously.
Whether you are replacing a failed manifold or refreshing an aging slide-out system, this unit is engineered to Lippert's specifications for multi-room hydraulic applications found across a wide range of Class A motorhomes, fifth wheels, and large travel trailers.
Eight hydraulic ports allow routing to multiple slide rooms and circuits from a single manifold body, reducing plumbing complexity.
Built-in flow divider meters fluid evenly across all active circuits, preventing one slide room from starving or overpowering another.
Engineered to Lippert specifications for a direct drop-in replacement in compatible multi-room hydraulic slide-out systems.
Backed by Lippert's limited 1-year manufacturer warranty for peace of mind on a critical drivetrain component.
In a multi-room hydraulic slide system, the manifold acts as the central distribution hub. Hydraulic fluid under pressure enters the manifold from the pump and power unit, and the manifold directs that flow to each individual slide cylinder. The flow divider inside the 173475 ensures that even when multiple slides are operated simultaneously, each receives a metered and balanced share of hydraulic pressure -- reducing the risk of uneven extension, binding, or mechanical overload.
Over time, manifold bodies can develop internal leaks, cracked ports, or corroded fittings that compromise the entire slide system. Replacing the manifold with a correct OEM-specification unit like the 173475 restores proper system balance and protects the downstream cylinders and seals.
The Lippert 173475 is designed for multi-room hydraulic slide-out systems as used across Lippert's HappiJac and Lippert-branded slide systems found on many Class A diesel and gas motorhomes, large fifth wheels, and toy haulers from major manufacturers including Forest River, Coachmen, Keystone, Jayco, and others. If your RV uses a Lippert multi-room hydraulic slide system with an 8-bank manifold configuration, this is the correct replacement part.
Replacing a hydraulic manifold requires depressurizing the hydraulic system, draining or capping lines to prevent fluid loss, and carefully labeling each hydraulic line before removal so ports can be reconnected correctly. The system must be bled of air after installation and tested at operating pressure before the rig is considered road-ready.
