EPDM sponge rubber compartment door weatherstrip with exclusive Peel-N-Stick skirting design. Delivers a positive weathertight fitment that many standard bulb designs cannot match. Replaces old, worn, or damaged seals on RV compartment doors, cabin doors, and hatches. Clean finished appearance with no unsightly gaps. Hand crafted and made in USA.
The Steele Rubber Products 90-3470-272 is a 1/2" wide by 7/16" high EPDM sponge rubber compartment door weatherstrip with an exclusive Peel-N-Stick skirting design. It replaces old, worn, or damaged seals on RV compartment doors, cabin doors, and hatches — delivering a positive weathertight fitment that many standard bulb-style designs cannot provide. The unique profile geometry seats firmly against the door frame surface, eliminating the gaps and irregularities that allow water, wind, dust, and pests to work their way past a degraded or ill-fitting bulb seal.
The skirting design is the key performance and longevity differentiator. A low-profile skirt extends along the base of the seal, covering the exposed edges of the 3M bonded adhesive tape. This protects the adhesive from direct exposure to road debris, moisture, UV, and cleaning solvents that progressively degrade unprotected adhesive edges and cause seal lift-off over time. The result is a seal that not only installs cleanly — leaving no visible gaps between the seal base and the door frame surface — but also maintains its bond through years of RV use. Application temperature range is 60–104°F (15–40°C), and surfaces should be at similar temperatures to achieve optimal adhesion. Available by the foot and in 15 ft and 30 ft pre-cut lengths.
Unique profile geometry delivers a positive seal against the door frame that many standard bulb designs cannot match — no gaps, no rocking, no inconsistent contact
Low-profile skirt covers the exposed edges of the adhesive tape, protecting the bond from debris, moisture, and UV — for a longer-lasting grip than seals with unprotected adhesive edges
Skirted base eliminates the unsightly gap between the seal edge and the door frame surface — a neat, professional look on compartment doors, hatches, and cabin doors
3M bonded adhesive backing makes installation quick and clean — no additional adhesives, primers, or tools required for standard applications
The 90-3470-272 is a general-application compartment door weatherstrip designed to fit a wide range of RV door and hatch frame configurations. No specific RV model or brand fitment list is available — this seal is selected by profile measurement rather than by make or model. Common Applications: • Storage Compartment Doors: Underbelly and exterior storage bay doors on travel trailers, fifth wheels, and motorhomes where the original foam or bulb seal has compressed flat or pulled away from the frame • Cabin Doors: Interior and exterior cabin door frames where a low-profile skirted seal provides a cleaner fit and finish than a round bulb profile • Hatches: Battery compartment hatches, generator access panels, utility bay hatches, and roof access hatches where a positive compression seal is required • Utility and Access Panels: Any framed access panel where the opening gap calls for a 1/2" wide by 7/16" high rectangular sponge seal To confirm correct fitment, measure the width and height of the existing seal or the door frame channel. This seal measures 1/2" W x 7/16" H. If the channel or gap is significantly wider or taller, a different profile size may be required.
Proper surface preparation and application conditions are critical to achieving a lasting bond with the 3M Peel-N-Stick adhesive backing: • Clean the surface thoroughly: Remove all traces of old adhesive, dirt, oil, wax, and moisture from the door frame before applying the new seal. Use isopropyl alcohol or an equivalent surface cleaner • Application temperature: Install only when both the seal and the bonding surface are between 60°F and 104°F (15°C and 40°C). Cold surfaces below 60°F will significantly reduce initial adhesive tack • Match surface temperatures: The temperature difference between the seal and the bonding surface should be as small as possible for optimal adhesion • Press firmly: After positioning, press the seal firmly along its full length to maximize adhesive contact with the surface • Allow cure time: Avoid repeated door opening and closing for several hours after installation to allow the adhesive bond to develop full strength • Measure before cutting: Cut each run to length before peeling the release liner — repositioning after the adhesive contacts the surface weakens the bond
Step-by-Step Installation: 1. Remove the Old Seal: Peel away the existing seal. Use a plastic scraper to remove any remaining adhesive residue from the door frame surface without scratching the substrate 2. Clean the Surface: Wipe the door frame thoroughly with isopropyl alcohol or equivalent surface cleaner. Remove all oil, wax, dirt, and moisture. Allow to dry completely before proceeding 3. Check Temperature: Confirm that both the seal and the door frame surface are between 60°F and 104°F. Do not install in cold conditions — adhesive tack is significantly reduced below 60°F 4. Measure and Cut: Measure each side of the door frame and cut the seal to length before peeling the adhesive liner. Miter cuts at 45° produce the cleanest corner joints 5. Dry-Fit First: Position the cut lengths around the door frame without removing the liner to confirm fit and corner alignment before committing to adhesive contact 6. Peel and Press: Starting at one corner, peel back a few inches of the release liner and align the seal on the frame surface. Press firmly as you progressively peel and apply along the full run 7. Press Along Full Length: Once positioned, run your thumb or a roller firmly along the entire length of the seal to maximize adhesive contact with the surface 8. Allow Cure Time: Avoid repeated door cycling for several hours to allow the adhesive bond to reach full strength before regular use 9. Check Compression: Close the door and verify the seal compresses evenly with no gaps or lifted sections around the full frame perimeter

Standard adhesive-backed seals bond directly to the surface with the adhesive tape edges exposed on both sides of the seal base. Over time, those exposed edges become entry points for road debris, moisture, and cleaning chemicals that lift the adhesive and cause the seal to peel away from the frame. The Steele Rubber exclusive skirting design addresses this failure mode directly. A low-profile skirt extends outward from the base of the seal on both sides, laying flat against the door frame surface and covering the adhesive tape edges completely. This produces three simultaneous benefits: • Cleaner appearance: No visible gap between the seal base and the frame — the skirted edge blends flush with the surface • Protected adhesive edges: The covered tape edges resist moisture infiltration, debris accumulation, and solvent attack that degrade unprotected bonds over time • Debris exclusion: The skirted edge prevents dirt, grit, and water from collecting in the gap behind the seal — eliminating a moisture trap that accelerates frame corrosion and adhesive failure The result is a seal that looks better on installation and holds its bond significantly longer than a standard rectangular sponge seal with exposed adhesive edges.
The skirting design is not a superficial styling difference — it directly addresses the two most common failure modes of adhesive-backed compartment door seals: exposed adhesive edge degradation and debris accumulation behind the seal base. On an RV that travels thousands of miles per year through varying temperature and weather conditions, those two failure modes are the primary reason compartment door seals need to be replaced every few seasons. The skirted design significantly extends the interval between replacements.
