EPDM rubber flat blade wiper seal with ball tip wiper and edge guide. 1/8" H x 3" W — 60 ft roll. Found on many RV slide-outs. Compatible with 1" companion bulb seal. Also known as 70-3709-265.
The Steele Rubber Products 90-3407-265 is a 3" Flat Blade Wiper Seal with Peel-N-Stick — an EPDM rubber wiper weatherstrip found on many RV slide-outs, used to create a dynamic seal that keeps weather, moisture, insects, and foreign elements out of the coach. The flat blade design flexes inward or outward in response to slide-out movement, maintaining consistent wiping contact against the slide-out surface during both extension and retraction.
The 70-3709-265 profile includes a ball tip wiper at the blade's leading edge for improved wiping action and reliable wiper flip as the slide-out moves, along with a wiper edge guide that aids installation by keeping the blade straight and providing a neat, well-aligned finished appearance. Manufactured from top-quality EPDM rubber for durability, wear resistance, and a proper seal — it will not fade, shrink, or crack through seasons of outdoor RV use.
This wiper seal is designed to work in conjunction with a companion 1" bulb weatherstrip or 1" Ribbed Hollow Bulb Weatherstrip, sold separately. The 60-foot roll provides generous coverage for a full slide-out perimeter replacement, multi-side applications, or larger RV configurations where a shorter roll would fall short.
Ball tip at the blade edge improves wiping action and ensures reliable wiper flip during slide-out extension and retraction
Built-in edge guide aids installation alignment, keeping the blade straight for a clean, well-appearing result on the RV
Pre-applied adhesive backing for tool-free installation — peel, press, and bond directly to the RV frame
Top-quality EPDM rubber — superior wear and weather resistance, will not fade, shrink, or crack
This wiper seal is designed to work in conjunction with a companion 1" bulb seal, sold separately. Compatible companion options include the 1" Bulb Weatherstrip and the 1" Ribbed Hollow Bulb Weatherstrip. The wiper alone does not provide a complete slide-out seal system — the bulb seal compresses against the RV body when the slide-out is closed. Confirm you have or are ordering the correct companion bulb seal before purchasing. Installation Temperature: Apply between 60°F and 104°F (15°C–40°C) for best adhesive bond strength. The temperature difference between the seal and the bonding surface should be as small as possible. Completely remove all old seal material, adhesive residue, dirt, wax, and moisture before applying, and wipe with isopropyl alcohol to ensure a clean, dry surface.
