EPDM rubber with flexible metal core. Push-on installation for 3/16" flanges. 2-7/8" H x 3/4" W — 40 ft roll. Black. Ideal upgrade for most RV brands.
The Steele Rubber Products 70-4349-265 Side Bulb Push-On Wiper Seal is a high-quality all-in-one wiper and bulb weatherstrip engineered to seal the sides of your RV slide-out when it is fully retracted, protecting your coach interior from moisture, wind, and insects. Unlike channel-based bulb seals that require a separate track receiver, this push-on wiper clamps directly onto the existing flange — making it one of the most straightforward slide-out seals to install or upgrade.
Constructed from premium EPDM rubber with an encased flexible metal core, the seal maintains its shape and grip on the flange through years of slide-out cycles, road vibration, and temperature extremes. The metal core provides the clamping force needed to keep the seal firmly on the 3/16" flange without adhesive or fasteners, while the EPDM outer shell resists fading, shrinking, and cracking. The 40-foot roll provides ample coverage for full perimeter replacement on large slide-outs or simultaneous replacement across multiple seals.
Encased metal core provides secure clamping grip on 3/16" flanges — no adhesive or fasteners required
Side-mounted bulb seals against the RV body when the slide-out is closed, blocking moisture and insects
Simply push the seal onto the existing flange — ideal upgrade or direct replacement for most RV brands
Will not fade, shrink, or crack. Superior weather resistance for full-time and seasonal RV use
This seal is designed to fit flanges 3/16" thick. Before ordering, measure the thickness of your existing slide-out flange to confirm it matches. The push-on metal core is sized specifically for this flange dimension — installing on a thicker or thinner flange may result in a loose fit or prevent the seal from seating properly. This seal is described as an ideal upgrade or replacement for most RV brands, but compatibility is not guaranteed for all models and configurations. Inspect your existing wiper seal type and mounting flange carefully before purchasing.
