Custom-designed replacement wiper seal for cable-operated RV slide-out systems. 100% EPDM rubber with reinforced stem, crown tab, and ball-tipped wiper. Commonly found on Forest River and Keystone RVs. Best value length for full RV reseal jobs. Hand crafted and made in USA.
The Steele Rubber Products 90-3420-265 is a unique, custom-designed replacement wiper weatherstrip engineered specifically for cable-operated RV slide-out systems. Unlike generic or universal slide-out seals, this weatherstrip is a direct-fit replacement for the original seal used on cable-powered slide-outs, installing by simply pressing the insertion stem into the existing track — no adhesives, no special tools required.
Constructed entirely from a proprietary EPDM rubber compound that delivers superior wear and weather resistance, this seal features meaningful engineering improvements over the original: a significantly reinforced insertion stem and wiper-stem junction point that prevents tearing and keeps the seal firmly seated in its track, a crown tab that increases wiping strength and prevents water intrusion while providing a clean finished look, and a ball-tipped wiper that improves wiping action and ensures the seal moves properly with the slide-out box during extension and retraction. The 60 ft strip is the best value length for complete RV reseal jobs involving multiple slide-out sections. Also sold under part number 70-4184-265, this seal is also available in 15 ft and 30 ft lengths and by the foot.

This press-in slide-out wiper seal is designed for cable-operated slide-out systems and is commonly found on the following RV brands: Forest River — Travel trailers, fifth wheels, and toy haulers with cable-operated slide-out systems Keystone — Travel trailers and fifth wheels with cable-operated slide-out systems This is a direct-fit replacement for the original press-in wiper seal used in these cable-powered slide-out tracks. It is not intended for hydraulic, rack-and-pinion, or electric motor slide-out systems that use different seal profiles. Compatibility is not guaranteed. Always verify that your slide-out uses a cable-operated system and that the track accepts a 2" wide press-in wiper seal before ordering. Actual fit may vary based on individual model year and manufacturing variations. Steele Rubber Products offers a Wiper Seal Sample Pack to help confirm the correct profile before purchasing.
This seal is specifically engineered for cable-operated slide-out systems and is not a universal slide-out seal. Before ordering, confirm the following: • Slide-Out Type: Your RV must have a cable-operated (not hydraulic, rack-and-pinion, or electric motor) slide-out system • Track Width: The existing seal track must accept a 2" wide press-in wiper weatherstrip • Seal Height: The installed seal height is 3/4" — verify this matches the clearance requirements of your slide-out box • Total Length Needed: Measure the perimeter of all slide-out sections to be resealed before selecting a strip length If you are unsure of your slide-out type, consult your RV owner's manual or contact your RV manufacturer to confirm the slide-out mechanism before purchasing.
Step-by-Step Installation: 1. Retract Slide-Out: Fully retract the slide-out box to expose the full length of the existing seal and track 2. Remove Old Seal: Pull the worn or damaged wiper seal out of the press-in track along its full length 3. Clean the Track: Remove all debris, old rubber fragments, and dirt from inside the track channel 4. Cut to Length: Measure and cut the new seal strip to the required length 5. Align Insertion Stem: Position the insertion stem of the new seal at one end of the track opening 6. Press Into Track: Firmly press the insertion stem into the track channel along the full length — a rubber mallet or dead-blow hammer works well to fully seat the stem 7. Verify Seating: Confirm the stem is fully and uniformly seated along the entire length with no gaps or unseated sections 8. Test Operation: Slowly extend and retract the slide-out to confirm the wiper moves correctly and the seal remains seated

Add 10% for cutting allowance.
The Steele Rubber press-in seal addresses the most common failure points of the original cable slide-out seal: stem tearing, junction separation, and insufficient wiping strength. The reinforced construction and upgraded wiper tip design make this a meaningful upgrade over the factory seal for long-term, reliable slide-out weatherproofing.
