Black Rubber 018-312-EKD D-Seal 1in x 15/16in x 35ft - Slide Out Seal

In this review of the Black Rubber 018-312-EKD D-Seal, the bottom line is simple: this is a practical, no-nonsense replacement seal for RV slide outs and interior protection. The reviewer found it best suited to owners who need a straightforward way to restore a positive seal or add interior bumper protection, and the single biggest reason to buy is the system design that lets the D-seal slide onto a base track that hides fasteners and creates a reliable barrier. The review highlights ease of installation and long-term durability from UV inhibitors while noting the adhesive can be mixed in performance.

Key Features

• System design: A two-part setup with a straight-edged base and a D-seal that slides on provides a neat finished look and hides mounting fasteners for a cleaner installation.
• Easy installation: The base includes adhesive backing for quick alignment and can be secured with fasteners if extra hold is needed, so one person can usually install it.
• Durability: Built-in UV inhibitors help the rubber resist sun damage for longer life when used outdoors on slide out edges.
• Versatile use: Works for new installations, upgrades to worn seals, or as an interior bumper when the slide out is extended.
• Exact fit dimensions: The 1in width by 15/16in height and 35ft length make it suitable for standard slide out runs where that size is required.
• Support and assurance: Two years of quality assurance plus free return and exchange provide reassurance if the product does not meet expectations.

Who It's For

This product is aimed at RV owners, DIYers, and repair shops needing a dependable replacement for a worn slide out seal or those installing a new seal system where a D-seal track is preferred. It suits anyone who values a tidy installation that hides fasteners and prefers the option of adhesive-backed placement with the ability to add mechanical fasteners.

Those who should look elsewhere are buyers who need a different cross-section size or length than 1in x 15/16in x 35ft, or customers who expect flawless adhesive performance in every climate without planning to supplement with mechanical fasteners. Also consider a different profile if your slide out requires a unique seal shape.

Pros & Cons

Pros

• Easy to align and install using the straight-edge base and adhesive backing.
• Quality rubber with UV inhibitors gives better longevity in sun exposure.

Cons

• Adhesive quality is mixed in user reports, so some installations may require additional fasteners.
• Limited to the stated cross-section and 35ft length, so it will not fit jobs needing other sizes.
