Buick GS 400 Weatherstrip & Seals - OEM-Fit Door, Trunk & Window Seals
Stop leaks, drafts, and road noise in your Buick GS 400 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 GS 400—restoring a tight, quiet seal around your doors, trunk, hatch, and windows.
Our Buick GS 400 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 GS 400, 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 GS 400.
