Source and compare custom automotive weatherstrips, EPDM door seals, glass run channels, trunk and hood seals, edge trims and drawing-based OEM profiles for vehicle manufacturing and aftermarket projects.
Start with a product or profile reference, then compare its section and mounting method with your vehicle opening.
Review the door-seal profile and application information before requesting a fit assessment.
Compare door and trunk sealing references with the installation interface and working gap.
Review OEM development inputs, sample evaluation and manufacturing requirements.
These references do not guarantee fit for a particular vehicle. Confirm the cross-section, mounting interface and required length before ordering; sample availability and supply terms require review.
Automotive weatherstrip demand includes vehicle-specific replacement seals, aftermarket profiles and drawing-based OEM components. Buyers should separate universal profiles from application-specific parts and confirm flange geometry, working gap, compression, joining, coating or flocking, annual volume and validation requirements.
Use an existing profile only after checking the cross-section and mating geometry. For a vehicle-specific part, send the installation position, end-view dimensions, physical sample or drawing, target quantity and required validation method.
A profile that fits one body opening should not be assumed to fit another. Select the development route from the installation interface and required function.
| Application | Key interface inputs | Common validation focus |
|---|---|---|
| Door opening seal | Body flange, working gap, compression, corner route, clips or retainers | Closing effort, water path, wind noise, retention and corner fit |
| Trunk / luggage seal | Flange geometry, deck-lid gap, water channel and joint location | Water management, compression continuity and splice position |
| Hood seal | Mounting interface, heat exposure, airflow path and under-hood fluids | Retention, temperature exposure and interference |
| Glass run channel | Glass thickness, channel geometry, travel path, flocking/coating and corner design | Glass movement, noise, insertion force and surface wear |
| Clip-on edge trim seal | Flange thickness, grip range, bulb position, bend radius and carrier | Pull-off, corner retention, compression and surface marking |
Vehicle/platform, installation position, drawing revision, section and overall routed length.
Solid/sponge zones, hardness, carrier, flocking, coating, adhesive, clips and joined ends.
Datums, dimensions, tolerance classes, compression targets, splice and corner acceptance.
Prototype and annual volume, validation plan, documentation, packaging and destination.
Catalog photographs show profile families, not guaranteed vehicle compatibility. Confirm fit using the actual body interface, approved drawing or authorized reference sample.
Universal profiles may be suitable for repair or general aftermarket use after fit testing.
Vehicle-specific profiles require matching geometry, routed length, corners, joints, retainers and validation criteria. A similar cross-section alone does not establish interchangeability.
Review materials, profile development, joined-frame options and RFQ requirements for custom vehicle sealing programs.
