Buick Special Weatherstrip & Seals - OEM-Fit Door, Trunk & Window Seals

Stop leaks, drafts, and road noise in your Buick Special with precision-fit replacement weatherstrip and seals designed specifically for your vehicle. Each seal is engineered to match the original profile and mounting groove of your Buick Special—restoring a tight, quiet seal around your doors, trunk, hatch, and windows.

Our Buick Special weatherstrip is manufactured from durable, weather-resistant rubber compounds such as EPDM, engineered for an exact OEM-quality fit and finish. These materials resist sunlight, ozone, and chemical exposure while maintaining flexibility across temperature extremes, so your new seals stay soft and pliable instead of cracking or hardening the way factory-original rubber does over time.

Use the Vehicle Selector above to find the correct weatherstrip for your Buick Special, or browse below to explore available options. Whether you’re chasing down a stubborn water leak or completing a full restoration, Factory Interiors makes it easy to achieve a tight, factory-quality seal with precision-fit weatherstrip for your Buick Special.
