When your hydraulic slide-out system needs a service or rebuild, the Lippert 140526 gives you everything required to restore full manual override and isolation control across all four slide-out rooms. This complete kit includes the 4-room manifold, valve sub-assemblies, mounting plate, IRC knobs, and all fastening hardware -- so you are not hunting for individual components at the shop or jobsite.
The IRC (Isolation Relief Control) valve is a critical serviceability feature on Lippert hydraulic slide-out systems. When the slide-out motor or control system fails, the IRC allows each room to be manually retracted or extended independently -- a necessity for getting your coach road-ready or into a service bay without full system power.
Part number 140526 is the complete 4-room version of this assembly, covering coaches with four hydraulic slide-out rooms on a single manifold circuit. The included plate provides the mounting structure, keeping all four valve sub-assemblies and their knobs organized and accessible in one location.
Includes the 4-room manifold, 4 valve sub-assemblies, mounting plate, 4 IRC knobs, and all required hardware -- no separate sourcing needed.
Simple quarter-to-half-turn knob action opens or closes each room's hydraulic circuit, enabling controlled manual slide-out movement during a power failure or service event.
Direct factory-spec replacement for Lippert hydraulic slide-out systems originally equipped with a 4-room IRC manifold assembly. Matches OEM fit and function.
Entire kit weighs 3 lbs., making installation manageable without special lifting equipment. Hardware is included so installation is self-contained.
IRC stands for Isolation Relief Control. In a Lippert hydraulic slide-out system, the IRC valves are the service tech's primary tool for manually cycling slide-outs when the pump, motor, or electrical system is non-functional. Each valve in this assembly corresponds to one slide-out room. Turning the knob isolates that room's hydraulic circuit, allowing controlled retraction using manual pressure or the system's hydraulic hand pump (if equipped).
Without functional IRC valves, a stuck slide-out can trap a coach at a campground or in a repair bay. Keeping this assembly in good working order -- or replacing a worn or leaking unit before a major trip -- is straightforward preventive maintenance for any 4-room hydraulic slide-out coach.
The 140526 is a drop-in replacement for the existing 4-room IRC manifold on compatible Lippert hydraulic systems. Installation typically involves:
This assembly is designed for Lippert hydraulic slide-out systems with 4-room IRC manifold configurations. It is a direct OEM-replacement part. If your coach has a 2-room or 3-room hydraulic slide-out system, a different IRC assembly part number will be required -- verify your existing manifold room count before ordering.
