Superior grade 100% EPDM sponge rubber rectangular extrusion with bonded 3M Peel-N-Stick adhesive. Versatile square-edge profile fits existing channels, adheres to flat surfaces, covers screw tracks, and dampens vibration. Ideal for replacing worn compartment door, hatch, and window seals on a wide range of RVs. Can be mitered for custom corner and radius fits. Hand crafted and made in USA.
The Steele Rubber Products 83-1031-277 is a 5/8" high by 1" wide superior grade EPDM sponge rubber rectangular extrusion with a bonded 3M Peel-N-Stick self-adhesive strip. Where half-round and hollow profiles are optimized for specific door frame geometries, the flat square-edge rectangular profile is one of the most versatile weatherstrip cross-sections available — it seats flush in existing rectangular channels, adheres cleanly to flat door frame surfaces, and can serve as a screw track insert cover or vibration dampening pad where needed. The taller 5/8" height provides substantial compression depth, making it well-suited for door and hatch frames with a wider gap between the door face and the frame surface.
Constructed from 100% EPDM sponge rubber, this extrusion resists moisture, ozone, and UV exposure and will not fade, shrink, or crack through years of outdoor RV use. The rectangular profile can be easily mitered or shaped when cut and bonded with a cyanoacrylate adhesive such as Super Bonder 495 to fit corners, curves, and custom radii — or bonded end-to-end to form a continuous one-piece gasket around a full door perimeter. This seal is often used alongside a Window Edge Weatherstrip when sealing RV window frames. Available in 10 ft and 30 ft pre-cut lengths and by the foot, backed by Steele Rubber Products’ 100% Satisfaction Guarantee.
Flat-sided 5/8" H x 1" W cross-section seats flush in existing rectangular channels and on flat door and hatch frame surfaces
100% EPDM sponge rubber resists moisture, ozone, and UV — will not fade, shrink, or crack through years of outdoor use
Highly weather-resistant 3M adhesive backing bonds immediately on contact for tool-free installation on clean, dry surfaces
Easily mitered or shaped when cut and bonded with Super Bonder 495 — fits corners, curves, and custom radii; end-to-end bonding creates a one-piece gasket
The rectangular square-edge profile is a versatile general-application extrusion suited for a wide range of RV sealing needs: Exterior Compartment Doors: Replaces worn or missing rectangular-profile seals on storage bay and utility compartment door frames Roof Hatches and Skylights: The flat rectangular cross-section seats cleanly in hatch frame channels, providing a weathertight compression seal around roof openings Entry Doors and Access Panels: Suitable for replacing rectangular-profile seals on entry doors and access panels where a taller compression height is required Window Frames: Pairs with the Steele Rubber Window Edge Weatherstrip for full window frame sealing — commonly used together on RV window perimeter applications Screw Track Insert Cover: The rectangular profile and EPDM construction make it suitable for covering exposed screw tracks or fastener channels to protect against moisture infiltration Vibration Dampening: The sponge rubber construction absorbs vibration when used as a cushioning pad between components or panels No specific RV model fitment list is available for this part. The rectangular profile is a general-application seal. Always verify that the 5/8" H x 1" W profile fits your specific door frame channel or surface before ordering.
The bonding surface must be completely clean and dry before applying the seal. • Remove all old seals, adhesive residue, and debris using a general-purpose adhesive cleaner or rubbing alcohol • Allow the surface to dry completely — applying over wet cleaner prevents adhesion • Apply within the recommended temperature range: 60–104°F (15–40°C) • Minimize the temperature difference between the seal and the bonding surface • The 3M adhesive bonds immediately on contact — work a few inches at a time and do not remove all backing at once For corner joints and full perimeter gasket applications, bond mitered cuts end-to-end using a cyanoacrylate adhesive (Super Bonder 495 or equivalent super glue for rubber) to create a continuous one-piece seal with no gaps at the corners.
Step-by-Step Installation: 1. Remove Old Seal: Pull the existing weatherstrip from the channel or frame surface, working around the full perimeter 2. Clean the Surface: Remove all old adhesive, residue, and debris using adhesive cleaner or rubbing alcohol 3. Dry Completely: Allow the bonding surface to dry fully before applying the new seal 4. Check Temperature: Confirm both seal and bonding surface are between 60–104°F (15–40°C) 5. Cut to Length: Measure and cut strip sections using a sharp utility knife; miter cuts at corners if creating a full perimeter gasket 6. Bond Corner Joints (if needed): Apply Super Bonder 495 or equivalent cyanoacrylate to mitered ends and hold firmly until set 7. Peel & Apply: Remove the backing a few inches at a time — do not remove all backing at once 8. Press Firmly: Apply steady, even pressure along the full length as you go, ensuring full contact with the channel or surface 9. Allow to Cure: 3M adhesive bonds immediately on contact; allow adequate time to fully set before heavy weather exposure
In The Package: • One (1) continuous 10 ft strip of 83-1031-277 Peel-N-Stick Rectangular Sponge EPDM Extrusion Seal • 3M adhesive backing pre-applied and protected by release liner Recommended Supplies (Not Included): • Adhesive cleaner or isopropyl rubbing alcohol for surface preparation • Disposable rags or shop towels • Sharp utility knife for cutting seal to length and mitering corners • Super Bonder 495 or equivalent cyanoacrylate adhesive for corner and end-to-end bonding • Steele Rubber Window Edge Weatherstrip (sold separately) if sealing full RV window frames
The rectangular profile’s flat square edges make it well-suited for custom fitting on complex door and hatch perimeters: Mitered Corners: Cut each section at a 45° angle at the ends, then bond the mitered faces together using Super Bonder 495 (cyanoacrylate adhesive) and hold firmly until set. This creates a tight, finished corner with no gap or overlap. One-Piece Perimeter Gasket: Cut and bond all four sections of a full door or hatch perimeter end-to-end using Super Bonder 495 before installation — the result is a single seamless gasket that can be dropped into the frame channel in one piece. Channel Installation: Where a rectangular channel already exists on the door frame, the seal can be pressed into the channel for a secure mechanical fit in addition to the adhesive bond — providing two retention mechanisms for high-use doors. Tip: When measuring for a full perimeter gasket, measure all four sides of the door opening and add 5–10% for cutting allowance on mitered corner cuts.
The rectangular square-edge profile is the most versatile cross-section in the Steele Rubber Products peel-and-stick extrusion lineup — equally at home as a channel-mounted door seal, a surface-adhered hatch gasket, a screw track cover, or a vibration pad. The ability to miter and bond sections into custom one-piece gaskets sets it apart from profiles that can only be applied as straight strips.
