In this article, we’ll explore the different types of RV slideout seals, their common issues, and how to seal RV slide outs interior seals effectively.

Types of RV Slide Out Seal

RV slide out seals are essential for preventing water, dirt, and pests from entering your vehicle. These seals also help maintain the interior temperature by reducing drafts. Knowing the different types of RV slide out seals can help you choose the best one for your needs and ensure proper maintenance. Here are the main types:

Wiper Seal

The wiper seal is a flexible rubber seal that wipes the slide-out as it moves in and out. This seal helps to keep dirt and debris from entering the RV. Wiper seals are typically installed along the top and sides of the slide-out.

Durable Protector D-Seal

The D-seal is shaped like the letter “D” and is designed to provide a tight seal when the slide-out is extended. This type of seal is highly durable and provides excellent protection against water and air leaks.

All-Rounder T-Seal

T-seals are versatile and can be used in various applications within the slide-out mechanism. They have a T-shaped cross-section and offer good sealing properties. These seals are often used in conjunction with other seals for maximum effectiveness.

Slide Out Sweep Seal

The sweep seal, also known as a bulb seal, is a rounded rubber seal that compresses to form a tight seal when the slide-out is closed. This type of seal is essential for preventing water and air infiltration.

Common Problems with Slide Out Seals

While RV slideout seals are designed to be durable, they can encounter several issues over time. Here are some common problems and the potential damage they can cause:

Drying Out

Rubber seals can start to dry out if not properly maintained. Dry seals can crack and lose their ability to form a tight seal, allowing water and air to enter the RV.

UV Damage

Constant exposure to UV rays can cause the rubber compound to break down. UV-damaged seals become brittle and are more likely to crack and fail.

Glue Softening

In hot weather, the glue holding the seals can soften, especially on the top of the slide-out. This can cause the seal to peel away from the RV, leading to leaks and reduced insulation.

RV Slide Out Seals Maintenance

Proper maintenance is key to extending the life of your camper slide out seals. Here’s how to keep them in the best shape:

Regular Cleaning

Clean your seals often using a mixture of dish soap and water. This helps remove dirt and grime that can cause the seals to wear out prematurely.

Lubrication

Use RV seal lubricants like the 3-IN-ONE® RVcare Rubber Seal Conditioner to keep the seals flexible and prevent drying out. Apply the lubricant according to the manufacturer’s instructions.

UV Protection

If your RV is frequently exposed to the sun, consider applying a UV protectant to the seals. This can help prevent UV damage and extend the life of the seals.

How to Replace RV Slide Out Seals

Replacing RV slideout seals can seem intimidating, but with the right approach, it’s a manageable task. Here’s what you need to know:

Identify the Type of Seal

First, determine the type of seal you have. This can be done by examining the cross-section of the seal. Getting underneath the slide and looking up can help you identify the seal type.

Measure the Seal Dimensions

Measure the height and width of the seal to ensure you purchase the correct replacement. Compare these dimensions with those listed in your RV catalog.

Determine the Length

Measure the length of the seal you need to replace. Only measure the section you are planning to replace.

Check the Attachment Method

Most seals are attached the same way as the original. Check how your current seals are attached to ensure you install the new ones correctly.

Replacing an RV Slide Out Seal

1. Remove the Wiper Seal: Use a screwdriver to remove the screws at the bottom and top of the seal. Pull off the wiper seal carefully.

3. Install the New Seals: Attach the new seals in the same manner as the original ones. Make sure they are properly aligned and secured.
