RV Slide Out Seal 1 x 15/16 in 35 ft D-Seal Wiper Weather Stripping

In this review of the RV Slide Out Seal 1 x 15/16 in 35 ft D-Seal Wiper Weather Stripping, the bottom line is simple: this is a practical, durable replacement for worn slideout seals and a solid upgrade for most RV owners who need a near-factory fit. The reviewer found it easy to install and appreciated the built-in wiper design and adhesive-ready straight edge, which makes alignment straightforward. If the priority is a long-lasting black rubber seal with good slide capacity and UV resistance, this product delivers that core benefit.

Key Features

• Direct replacement: Sized to match common slideout profiles so it fits with most RV models and replaces worn factory seals without major trimming.
• Wiper design: The base includes a wiper that helps maintain a tight seal and smooth movement of the slideout, reducing drafts and noise.
• Adhesive-ready edge: A straight edge on the design makes alignment and bonding easier when using standard adhesive backing for secure installation.
• UV inhibitors: The rubber compound includes UV inhibitors for added longevity in sun-exposed installations, helping prevent brittle failure.
• Generous length: At 35 ft it covers long slideouts or multiple shorter runs, avoiding the need for multiple short pieces and seams.

Who It's For

This seal is aimed at RV owners, technicians, and DIYers who need a robust replacement for slideout weather stripping and want a product that closely matches factory profiles. It is particularly useful for those upgrading degraded rubber that no longer seals, or for installations where a long 35 ft length and built-in wiper reduce the number of joins.

It is less suitable for someone who requires soft, highly compressible foam seals for unusual gaps or who needs a custom extruded profile not described here. If an exact OEM part number is required for warranty purposes, buyers should confirm compatibility before installing.

Pros & Cons

Pros

• Easy to install with an adhesive-friendly straight edge and a wiper that snaps into channels for quick fitment.
• Positive reports on overall seal quality and durability, with customers noting a near-factory match.
• Built with UV inhibitors to extend lifespan in outdoor exposure.
• Long 35 ft length provides coverage for large slideouts and reduces seams.

Cons

• Material thickness drew mixed comments, so those expecting a very soft or very thick profile should verify fit before full installation.
• Black rubber may show wear in high-friction areas faster than some harder trim materials.
