The Lippert Components 387821 is a 1.5-inch hinged flap inwall seal designed for use on RV slide-out rooms. This inwall seal provides a critical barrier between the slide-out room and the RV interior wall cavity, helping to prevent drafts, moisture intrusion, insects, and road debris from entering the living space when the slide is deployed or retracted.
The hinged flap design allows the seal to flex and conform as the slide-out moves in and out, maintaining consistent contact and protection throughout the full range of motion. Built to Lippert's quality standards, this seal is a reliable OEM-compatible replacement for worn or damaged inwall slide-out seals found on a wide variety of RV brands and models that use Lippert slide-out systems.
Key Features:
This seal is sold by the foot or as a discrete component — refer to your RV's service manual or Lippert's documentation to confirm the correct quantity needed for your slide-out application. Lippert Components part number 387821 is a direct OEM replacement, making it easy to restore a proper seal to your slide-out room.
