Rubber D Shape Door Seal Strip 1 in RV Slide Out Seal - Heavy Duty

In this review of the Rubber D Shape Door Seal Strip 1 in, the bottom line is simple: this long, self-adhesive EPDM gasket is best for DIYers who need a heavy duty, waterproof seal for doors, slides and vehicle hatches. The product stands out because of its 35 ft length and thick, durable rubber that resists cold and UV, making it a practical solution when the goal is to stop drafts, noise and water from entering gaps. Its self-adhesive backing speeds installation for one-off repairs or long runs.

Key Features

• Comprehensive package: Ships as one continuous 35 ft strip so you have enough material to cover long runs without joining multiple pieces.
• Quality construction: Made from black EPDM rubber for long term resistance to weather, UV and low temperatures so it will not become brittle or break easily.
• Self-adhesive backing: Built-in adhesive tape allows quick placement and a strong initial hold so most installations require only measuring and pressing in place.
• Proper dimension: At roughly 1.0 in wide by 1.1 in high with about 0.12 in wall thickness, it provides a substantial D-shaped seal that fills medium to large gaps effectively.
• Versatile use: Designed for doors, windows, RV slide outs, cars, trucks and boats to reduce wind, dust, noise and water intrusion in many environments.
• Easy to customize: Flexible and simple to cut with scissors so you can bend and trim it to fit awkward corners and hatch perimeters.

Who It's For

This strip is aimed at homeowners, RV owners and vehicle owners who need a long, heavy duty gasket for sealing slide outs, doors or hatches where a resilient, weatherproof seal is required. It is especially useful for projects that need a continuous length up to 35 ft without many joins.

It is less appropriate for tiny precision sealing jobs where an ultra-thin or factory-matched profile is required, or where customers need a permanent mechanical fastener rather than an adhesive bond; those users should consider a different trim or professionally installed gasket.

Pros & Cons

Pros

• Durable EPDM material resists UV, weather and freezing temperatures for long service life.
• Large 35 ft length covers long runs without splicing, useful for RV slide outs and full door perimeters.
• Self-adhesive backing enables fast, tool-light installation for most DIY jobs.
• Generous D-shape thickness provides good sound and water sealing performance.

Cons

• Adhesive quality has mixed reports; some users may need additional fasteners or contact adhesive for a long-term hold.
• The profile is substantial and may be overkill for very small gaps or where a thin factory-style gasket is required.
