Stop leaks, drafts, and road noise in your GMC G1500 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 GMC G1500—restoring a tight, quiet seal around your doors, trunk, hatch, and windows.
Our GMC G1500 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 GMC G1500, 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 GMC G1500.
Designed for GM full-size vans from 1971 to 1980, this windshield seal is a perfect fit for Chevrolet and GMC models like the G10, G20, and G30. Replacing OEM #3062392, this black gasket is crafted without a trim groove and is made from durable, ozone-resistant EPDM polymer for long-lasting performance. It is designed to be installed during glass replacement, with the seal placed on the body first, followed by the glass, and secured with a self-locking strip. This ensures a snug fit that reduces drafts and road noise while maintaining an accurate seal profile. Whether you're restoring your van or replacing a worn-out seal, this part is built to original specifications for a reliable fit and function. Backed by a 90-day warranty, it’s a dependable choice for your restoration or repair project.
