The Definitive Guide to Types of RV Slide Out Seals

RV slide-out seals are designed to provide a tight seal between the slide-out room and the RV when the slide-out is extended or retracted. Here are some common types of RV slide-out seals:

1. Wiper Seals

Wiper seals, also known as bulb seals or D-seals, are the most common type of slide-out seal. They consist of a rubber or vinyl bulb-shaped seal attached to a flexible base. When the slide-out is retracted, the wiper seal compresses against the RV wall, creating a tight seal to keep out water, drafts, and debris.

2. Flap Seals

Flap seals are flexible strips of rubber or vinyl that hang down from the slide-out room’s edge. They help to create a barrier between the RV and the slide-out, preventing water, wind, and dust from entering. Flap seals are often used in combination with wiper seals for added protection.

3. Brush Seals

Brush seals consist of rows of bristles made of synthetic material, such as nylon or polypropylene. They are attached to a mounting strip and create a barrier when the slide-out is closed. Brush seals are effective in keeping out dirt, insects, and drafts while allowing for easy movement of the slide-out.

4. Slide Topper Seals

Slide topper seals, also known as slide-out awnings or slide-out toppers, are fabric or vinyl covers that extend over the top of the slide-out room. They provide an additional layer of protection against water, debris, and UV rays. Slide topper seals are typically installed on larger RVs with larger slide-outs.

5. Bulb Seals

Bulb seals are similar to wiper seals but have a bulb-shaped profile. They are made of rubber or vinyl and create a seal by compressing against the RV wall when the slide-out is retracted. Bulb seals are commonly used on smaller RVs and slide-outs with a narrower space for the seal.

It’s important to regularly inspect and maintain the slide-out seals to ensure their effectiveness and prevent leaks or damage. Over time, seals may wear out or become damaged, requiring replacement. Consult the manufacturer’s guidelines or seek professional assistance to select the appropriate type of slide-out seal and ensure proper installation for your specific RV model.
