Superior grade 100% EPDM sponge rubber rectangular extrusion with bonded 3M Peel-N-Stick adhesive. Compact square-edge profile fits narrower existing channels and tighter door frame surfaces. Ideal for replacing worn compartment door, hatch, and window seals. Can be mitered and bonded for custom corner and radius fits. Hand crafted and made in USA.
The Steele Rubber Products 83-1033-277 is a 7/16" high by 11/16" wide superior grade EPDM sponge rubber rectangular extrusion with a bonded 3M Peel-N-Stick self-adhesive strip. 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. At 7/16" H x 11/16" W, this is the more compact of Steele Rubber’s rectangular EPDM extrusions, making it specifically suited for narrower door frame channels and tighter-clearance applications where the larger 5/8" H x 1" W rectangular profile would be too tall to allow proper door closure.
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 or hatch perimeter. Available in 10 ft and 30 ft pre-cut lengths and by the foot, this seal is backed by Steele Rubber Products’ 100% Satisfaction Guarantee.
7/16" H x 11/16" W square-edge cross-section fits narrower existing channels and tighter door frame surfaces where a taller profile would prevent proper closure
100% EPDM sponge rubber resists moisture, ozone, and UV — will not fade, shrink, or crack through years of outdoor RV use
Highly weather-resistant 3M adhesive backing bonds immediately on contact for tool-free installation on clean, dry door and hatch frame 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 seamless one-piece gasket
The compact 7/16" H x 11/16" W rectangular profile is well-suited for applications where the taller 5/8" H x 1" W rectangular extrusion would compress too much or prevent door closure: Exterior Compartment Doors: Replaces worn or missing rectangular-profile seals on storage bay and utility compartment door frames with narrower channel depths Roof Hatches and Skylights: Flat rectangular cross-section seats cleanly in shallower hatch frame channels for a weathertight compression seal around roof openings Entry Doors and Access Panels: Suitable for access panels and entry door applications where a moderate 7/16" compression height is needed without overfilling the door gap Window Frames: Can be used as a sealing extrusion on RV window frame perimeters where a low-profile rectangular seal is required Screw Track Insert Cover: The compact rectangular profile fits over narrower screw tracks or fastener channels to protect against moisture infiltration at the fastener line Vibration Dampening: EPDM sponge rubber construction absorbs vibration when used as a cushioning pad between components or panels in tighter spaces No specific RV model fitment list is available for this part. The rectangular profile is a general-application seal. Always verify that the 7/16" H x 11/16" 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, 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 83-1033-277 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 83-1031-277 Rectangular Extrusion (5/8" H x 1" W, sold separately) if a larger profile is required for the same application
Steele Rubber Products offers two sizes of this rectangular EPDM sponge extrusion. Choosing the right one depends on the depth and width of the door frame channel or the gap between the door face and the frame surface when closed: 83-1033-277 — 7/16" H x 11/16" W (This Item): The compact profile for narrower channels and tighter door frame gaps. Use when the door or hatch requires minimal compression height to close properly, or when the frame channel is too narrow for the larger extrusion. 83-1031-277 — 5/8" H x 1" W (Larger Profile): The standard-size rectangular extrusion for wider channels and larger door frame gaps. Provides more compression depth and a wider sealing footprint for doors and hatches with more clearance between the door face and the frame. Tip: Measure the depth of the existing channel or the gap between the door face and frame surface when the door is nearly closed. Select the profile whose height is slightly greater than the gap measurement to ensure proper compression contact without preventing full door closure.
The 7/16" H x 11/16" W compact rectangular profile fills the gap between the thinner half-round profiles and the full-size 5/8" H x 1" W rectangular extrusion — providing a mid-range compression height that fits a wide range of narrower RV compartment door and hatch channel depths that the larger rectangular extrusion would overfill.
