Weatherstrip & Seals - OEM-Fit EPDM Rubber Seals

Seal out wind, water, dust, and road noise with precision-fit automotive weatherstrip and seals manufactured to OEM specifications for your door, trunk, hatch, window, and window channel. Each seal is engineered to match the original profile and mounting groove of your vehicle’s factory application—restoring a tight, quiet seal and stopping the leaks and drafts that come with age.

Our 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, shrinking, or hardening the way factory-original rubber does over time.

Factory Interiors sources weatherstrip and seals from trusted manufacturers including Metro Moulded Parts and Fairchild Industries, giving you a wide range of factory-correct options for your vehicle. Use the Vehicle Selector above to find the correct weatherstrip for your year, make, and model, 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.
