EPDM rubber thin side lip push-on weatherstrip with rounded top and segmented steel core. No adhesive required — simply press onto flanges 1/16"–1/8" thick. Commonly found on Jayco Seneca, Precept, and White Hawk storage compartment doors. Black, 15 ft pre-cut strip. Also known as 70-3801-277.
The Steele Rubber Products 90-3717-277 is a Thin Side Lip Push-On Weatherstrip — an EPDM rubber seal with a rounded top profile and a segmented steel core that makes it ideal for dynamic, high-movement applications. Unlike adhesive-backed weatherstrips, this seal requires no glue or tape: simply align it over the door flange and press it into place. The segmented steel core grips the flange firmly and allows the seal to flex and bend around curved corners without losing its hold.
This profile is commonly found on Jayco Seneca and Precept Motorhomes and Jayco White Hawk Trailer storage compartment doors, making it a trusted OEM-style replacement for owners of those models. It fits flanges ranging from 1/16" to 1/8" thick, which covers the thin sheet metal flanges typical of RV exterior compartment door frames. Once installed, the seal creates a tight compression fit that protects the compartment interior from wind, dust, water, and debris.
The EPDM rubber construction ensures long-term performance through UV exposure, ozone, and temperature extremes — the seal will not fade, shrink, or crack over time. A tucking tool is recommended to assist in fully seating the seal along the flange, particularly on curved or tight-radius sections. The 15-foot pre-cut length is sized to service a single door perimeter or multiple shorter compartment door runs.
Encased-in-rubber steel core grips the flange firmly and flexes around curves — won't rust like inferior alternatives
Push-on installation — simply press onto the door flange for a tight, secure fit with no glue, tape, or surface prep needed

This seal is designed to fit flanges 1/16" to 1/8" thick. Measure your existing door flange before ordering to confirm compatibility. Flanges outside this range may not grip securely. Tucking Tool Recommended: A rubber or plastic tucking tool is recommended to fully seat the seal along the flange, especially on curved sections or tight corners. Do not use a metal screwdriver, which can damage the rubber or core. Trim the seal to length with scissors or a sharp utility knife for a clean fit.
Primary Part Number: 90-3717-277 Also Known As: 70-3801-277 Known RV Fitment (not exhaustive): • Jayco Seneca Motorhome — storage compartment doors • Jayco Precept Motorhome — storage compartment doors • Jayco White Hawk Trailer — storage compartment doors Available Lengths (Same Profile): • 15 ft — Part 90-3717-277 (This Item) • Also available by the foot for custom lengths Note: Compatibility is not guaranteed.

What You Need: No adhesive required. Recommended supplies: tape measure, scissors or utility knife, rubber or plastic tucking tool (sold separately). Basic Installation Steps: 1. Verify Flange Thickness: Confirm your door flange measures between 1/16" and 1/8" thick — the seal will not grip properly on flanges outside this range 2. Remove Old Seal: Pull the existing weatherstrip off the flange; remove any residual material from the flange edge 3. Measure & Cut: Measure the door opening perimeter and cut the seal to length with scissors or a utility knife 4. Press Onto Flange: Starting at one corner, press the seal channel firmly down over the flange edge by hand, working along the full perimeter 5. Use Tucking Tool: Run a rubber or plastic tucking tool along the seal to fully seat it on the flange, especially on curved sections and corners 6. Test the Closure: Close the compartment door to confirm the rounded lip compresses evenly and creates a consistent, gap-free seal
