Keep your slide-out room sealed tight against the elements with this OEM-spec Lippert rubber sweep. Designed as a direct replacement for worn or cracked bottom seals on Lippert slide-out systems, this sweep installs quickly and restores the barrier between your slide floor and the coach body -- blocking drafts, moisture, road dust, and insects.
The bottom sweep on a slide-out takes constant abuse -- it drags across the slide tray every time the room extends or retracts, and sits exposed to rain, road grime, and UV when parked. Over time the rubber compresses, cracks, or tears, leaving a gap at the base of the slide that lets in cold air, humidity, and pests.
Lippert part 117018 is the correct replacement sweep for slide-out systems that call for the #366 profile. Order by this part number to ensure you receive the exact profile, durometer, and cut length your system requires. Attempting to substitute a generic sweep with a different profile can result in poor sealing, accelerated wear, or interference with slide travel.
Lippert #366 profile ensures the sweep seats and compresses exactly as designed for Lippert slide carriers and wipe seals.
Supplied at 19 inches -- ready to install without field cutting on the slides it was designed for.
Flexible rubber compound resists UV degradation, ozone cracking, and compression set through repeated slide cycles.
Sourced directly through Lippert's parts program -- not an aftermarket approximation -- so fit and longevity match original specs.
Lippert uses several different sweep profiles across its slide-out product lines. Before ordering, confirm your system calls for the #366 profile. The easiest way to verify is to check the sweep currently installed -- the profile number is often embossed or printed on the rubber -- or cross-reference your slide-out serial number with Lippert's parts lookup.
The 19-inch length is specific to a subset of Lippert slide configurations. If your slide opening is wider, you may need multiple pieces or a longer cut -- contact Lippert technical support or your RV dealer's parts department with your slide serial number to confirm quantity and any additional pieces needed.
Bottom sweeps on Lippert slide-outs are typically retained by a metal wiper channel screwed to the underside of the slide floor or slide fascia. Installation generally involves:
Refer to your specific slide-out service documentation for torque specs on retaining hardware and any sealant recommendations at the channel ends.
