High-quality EPDM sponge rubber hollow D-profile seal with increased wall thickness, reinforced apex, and recessed adhesive design. Ideal for ramp gates and access doors. 3M Peel-N-Stick skirting adhesive. Black, 15 ft pre-cut strip. Also known as 70-3850-283.
The Steele Rubber Products 90-3456-272 is a 1" Hollow "D" Peel-N-Stick weatherstrip — a high-quality EPDM sponge rubber seal engineered specifically for demanding RV applications including ramp gates, access doors, and other openings that experience repeated, heavy compression cycles. The hollow D-profile compresses uniformly when the door or gate closes, creating a positive seal that keeps out moisture, debris, and weather.
What sets this profile apart from standard hollow seals is its increased wall thickness and reinforced apex. These design features work together to prevent compression set — the permanent deformation that occurs when a seal is repeatedly compressed and loses its ability to spring back — and maintain optimal sealing contact over the long term. The recessed adhesive design positions the adhesive backing inward from the seal edges, preventing moisture and debris from working into the adhesive and compromising the bond from the sides.
Installation is straightforward with the exclusive Peel-N-Stick skirting design: peel off the adhesive backing and press the seal firmly onto the prepared surface. The skirting surrounds the adhesive edges for a clean finished appearance, added adhesive protection, and a long-lasting surface grip. The 15-foot roll is right-sized for a single gate or door perimeter, or a targeted section replacement on an existing seal run.
Increased wall thickness and reinforced apex prevent compression set — maintains optimal sealing contact through repeated open/close cycles
Adhesive is recessed from the seal edges — prevents moisture and debris from collecting on the sides and undermining the bond
Exclusive skirting surrounds adhesive edges — clean finished look, adhesive edge protection, and long-lasting surface grip
High-quality EPDM sponge rubber — durable under harsh environmental conditions, weather, UV, and temperature extremes
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. Surface Preparation: Completely remove all old seal material, adhesive residue, dirt, wax, and moisture before applying. Wipe the bonding surface with isopropyl alcohol and allow to fully dry. Thorough surface prep is always recommended for a long-lasting bond.
Primary Part Number: 90-3456-272 Also Known As: 70-3850-283 Available Lengths (Same Profile): • 15 ft — Part 90-3456-272 (This Item) • 30 ft — Part 90-3457-272 • Also available by the foot for custom lengths Note: Application temperature 60°F–104°F. Fully prep surface before applying for best adhesive bond.
What You Need: No tools required for adhesive application. Recommended supplies: isopropyl alcohol, clean cloth, tape measure, scissors or utility knife. Basic Installation Steps: 1. Check Temperature: Confirm ambient temp is between 60°F and 104°F (15°C–40°C) — match surface and seal temperature as closely as possible 2. Remove Old Seal: Completely remove all old weatherstrip material and adhesive residue from the mounting surface 3. Clean & Dry: Wipe the bonding surface with isopropyl alcohol and allow to fully dry 4. Measure & Cut: Measure the gate or door perimeter and cut the seal to length with scissors or a utility knife 5. Peel & Press: Remove the skirted adhesive backing and press the D-profile seal firmly onto the mounting surface, working from one corner around the full perimeter 6. Test the Closure: Close the ramp gate or access door to confirm the hollow D compresses evenly, the reinforced apex springs back cleanly, and the seal creates a consistent, gap-free closure
