Black EPDM sponge rubber cushion strip with peel-and-stick adhesive backing for hatch sealing, compartment doors, vibration control, and window frame bracing.
The Steele Rubber Products 90-3457-272 peel-n-stick sponge cushion strip is a low-profile EPDM rubber strip designed for sealing, cushioning, and bracing applications. Its compressible sponge rubber construction helps provide a weather-resistant cushion where light compression is needed.
This strip is commonly used for marine hatch and compartment door sealing, vibration control, and window frame bracing. The peel-and-stick adhesive backing helps simplify installation on clean, dry, properly prepared surfaces.
Low-profile cushion strip measures 3/4" wide by 5/16" high
Adhesive backing helps simplify installation without separate glue
Compressible rubber material helps resist weather, moisture, and outdoor exposure
Hand crafted and quality manufactured by Steele Rubber Products
This is a universal cushion/weatherstrip profile and should be matched by measurements and application, not by vehicle, RV, or boat model alone. Before ordering, compare the original seal’s width, height, length, shape, compression gap, and mounting surface.
Before Starting: Install on a clean, dry surface within the recommended application temperature range. Adhesive-backed seals bond best when the mounting surface is free of dirt, wax, oil, old adhesive, and moisture. Basic Installation Steps: 1. Confirm Fit: Compare the 3/4" width and 5/16" height to the original seal or required compression gap. 2. Clean Surface: Remove old seal material, adhesive residue, dirt, wax, oil, and debris from the mounting surface. 3. Test Position: Dry-fit the strip before peeling the backing to confirm placement and length. 4. Cut to Length: Trim the strip with a sharp blade or scissors for a clean end cut. 5. Apply Gradually: Peel back a small section of liner at a time and press the strip firmly into place. 6. Avoid Stretching: Lay the strip naturally without pulling or stretching the rubber during installation. 7. Press Firmly: Apply even pressure along the full length to help the adhesive bond. 8. Allow Bond Time: Give the adhesive time to set before heavy compression, washing, or exposure to harsh conditions.
Package Contents: • Steele Rubber Products 90-3457-272 peel-n-stick sponge cushion strip • 15 ft length of black EPDM sponge rubber strip with adhesive backing NOT Included — May Also Need: • Surface cleaner or adhesive remover • Cutting tool • Measuring tape • Roller or hand pressure tool • Additional seal material if more than 15 ft is required This listing is for one 15 ft peel-n-stick sponge cushion strip only. Verify profile dimensions and total length needed before ordering.
To confirm compatibility before ordering, have the following ready: • Width and height of the original seal or required cushion profile • Total length needed • Photos of the old seal and mounting surface • Type of application: hatch, compartment door, window frame, cushion, or vibration control • Gap size when the door, hatch, or panel is closed Why this matters: Universal rubber seals can look similar but differ by profile shape, compression height, adhesive style, and material density. Matching the profile and compression gap helps prevent leaks, poor closure, or premature adhesive failure.
Match this cushion strip by profile size, material, compression gap, adhesive mounting surface, and total length needed.
If replacing the cushion strip does not correct the issue, inspect the latch, hinges, frame alignment, mounting surface, drainage path, and closure gap before selecting another seal profile.
