Wankic RV Slide-Out Seal 018-312-EKD 35-inch Black 1 in x 1 in Rubber wiper UV-resistant

Wankic RV Slide Out Seal 018-312-EKD is a 1" x 1" x 35" black replacement rubber seal designed to restore weatherproofing and smooth operation to RV camper slide-out systems.

Replacing a worn slide-out seal is a fast way to stop drafts, reduce noise, and protect your RV interior from dust and moisture. The Wankic 018-312-EKD fits most slide-out profiles and is sold as a single 35" length. Built with UV-resistant compounds and an easy-align base, this seal works for new installs or upgrades and includes a wiper edge to help maintain contact when the slide moves.

How will this seal improve my slide-out’s performance?

Installing the Wankic 018-312-EKD restores a tight barrier between the slide-out and RV body, reducing air infiltration and rattling. The integrated wiper edge keeps consistent contact as the slide extends and retracts, helping prevent wear on both the seal and adjacent surfaces.

• Stops drafts and reduces wind noise while driving or parked
• Wiper design maintains contact and minimizes scraping
• UV-stabilized rubber resists cracking from sun exposure
• Straight-edged base simplifies alignment during adhesive installation

Will this fit my RV slide-out system?

The profile measures 1 inch wide by 1 inch high and comes in a 35-inch length, suitable for many common slide-out channels. Because of the standardized base design, it pairs well with a variety of camper models; measure your original seal profile to confirm fit before ordering.

• 1" width x 1" height cross-section matches many OEM seals
• 35" single-piece length for smaller slide sections or splicing into longer runs
• Straight-edged base accepts adhesive backing for secure mounting
• Compatible with retrofit and replacement projects across RV makes

How do I install the 018-312-EKD slide-out seal?

Installation is straightforward for DIYers with basic tools. Clean the mounting surface, dry-fit the seal to ensure correct length, then use an appropriate adhesive or the included backing to secure the straight base. Trim excess material and press firmly along the full length to ensure continuous contact.

• Clean surface to remove old sealant, dirt, and oil
• Measure and trim the 35" seal to fit or splice with additional lengths
• Use high-quality adhesive designed for rubber-to-metal or rubber-to-fiberglass bonds
• Allow adhesive cure time per manufacturer instructions before operating slide

What materials and durability features should I expect?

The Wankic seal is molded from UV-resistant rubber compounds that slow degradation from sunlight and heat. The profile includes a built-in wiper to reduce abrasion and preserve the sealing surface, extending functional life compared with plain edge seals.

• UV inhibitors minimize cracking and hardening from sun exposure
• Flexible rubber maintains sealing pressure over repeated use
• Wiper edge reduces rubbing noise and surface wear
• Black finish blends with most RV exterior trims
