When your IIRC or MIRC full-turn slide-out system develops a valve failure, this OEM-spec Lippert replacement gets you back on the road without the guesswork. Part number 240529 is the correct direct-replacement valve assembly for all IIRC and MIRC full-turn slide-out systems, sourced from Lippert -- the manufacturer behind the majority of OEM slide-out systems installed in North American RVs.
Lippert IIRC (In-Room Integrated Rail and Carrier) and MIRC (Manual In-Room Carrier) slide-out systems are widely deployed across travel trailers, fifth wheels, and motorhomes from virtually every major OEM manufacturer. The valve assembly within these systems controls hydraulic or pneumatic actuation of the slide-out room, and a worn or failed valve is a common service item after years of seasonal use.
The Lippert 240529 is the factory-replacement valve assembly designed to restore proper operation to these full-turn systems. Using the correct OEM part number ensures proper fit and function -- aftermarket substitutes often lack the precise tolerances required for reliable full-turn slide-out operation.
Designed and supplied by Lippert specifically for all IIRC and MIRC full-turn slide-out systems -- no modification or adaptation required.
Drop-in replacement for the original valve assembly. Restores factory slide-out operation without cutting, welding, or fabrication.
Weighs just 0.05 lbs., making installation and handling easy, even in tight slide-out compartments with limited access.
Backed by Lippert's limited 1-year manufacturer warranty for peace of mind on the road or at the campsite.
Common symptoms of a failed valve assembly in IIRC and MIRC systems include a slide-out room that will not extend or retract fully, a room that drifts or creeps after deployment, unusual resistance during operation, or visible fluid seepage around the valve body. Replacing the valve assembly rather than the entire slide-out mechanism is typically a straightforward and cost-effective repair.
The IIRC (In-Room Integrated Rail and Carrier) system is Lippert's powered, motor-driven slide-out design commonly found in mid-range and premium RVs. The MIRC (Manual In-Room Carrier) is a related design variation. Both systems share this valve assembly (part 240529), which simplifies parts inventory for dealers and DIY owners who service multiple units.
Confirm your slide-out system is an IIRC or MIRC full-turn configuration before purchasing. Lippert produces several other slide-out architectures (SchwinTek, Power Gear, electric motor-driven rail systems) that use different service components. Your coach's owner documentation or the Lippert label affixed to the slide-out mechanism will identify the system type. Lippert's customer support line can also confirm compatibility by VIN or unit serial number.
