The Precision Windshield Weatherstrip Seal Without Trim Groove WBL 819 is a direct-replacement rubber seal designed to secure the windshield, keep out water and dust, and reduce wind noise and vibration. Engineered in a no-trim-groove profile for vehicles that use a flush rubber flange, this seal restores fit and finish during windshield replacement or restoration projects. Made from high-quality, weather-resistant rubber, it offers long-lasting flexibility, UV and ozone resistance, and reliable sealing performance while remaining easy to fit and adjust during installation.
Features:
- No-trim-groove WBL 819 profile for windshields that accept a flush rubber flange.
- Made from high-quality, weather- and UV-resistant rubber for long-lasting performance.
- Seals windshield edges to prevent water intrusion, dust entry, and wind noise.
- Flexible, compressible profile eases installation and conforms to glass and body contours.
- Ideal for restoration and replacement projects where an OEM-style rubber seal is required.
- Direct-replacement design restores fit and appearance without modifying the windshield or body.
Installation / Application:
- Difficulty: 2/5
- Estimated time: 30–90 minutes (may vary by vehicle and whether windshield is removed)
Instructions:
- If replacing an existing seal, carefully remove the old weatherstrip and any adhesive remnants using trim tools and a razor blade; protect paint and glass.
- Thoroughly clean the windshield flange and glass edge with isopropyl alcohol or recommended adhesive remover; allow to dry.
- Test-fit the new WBL 819 seal around the glass/frame to confirm orientation and fit; trim excess if necessary.
- If the windshield will remain in the vehicle and the seal is a push-in style, lubricate the rubber bead with a mild soapy solution and press the seal evenly into the flange starting at the top center and working outward around both sides.
- If the windshield must be removed and reinstalled, follow vehicle-specific procedures: apply recommended primer and urethane adhesive per manufacturer directions, set the windshield with suction cups, and seat the seal into the adhesive while ensuring correct alignment.
- Work the seal into the channel completely, using plastic pry tools to avoid pinching or distortion. Cut and finish any overlaps cleanly.
- Allow any adhesives or primers to cure per product instructions, then inspect for gaps and test for leaks with water once cured.
