Built for Sealing Performance

Sealing performance in automotive applications starts at the surface. North Coast Seal supplies custom-molded and extruded door and window seals engineered to provide weather resistance, noise reduction, and reliable protection from the elements.

From luxury vehicles to commercial fleets, today’s vehicles demand sealing systems that maintain comfort, durability, and aerodynamic efficiency over years of use. Our rubber extrusion solutions help OEMs and Tier 1 suppliers meet exacting performance specs for a wide range of vehicle platforms.

We work with EPDM, TPE, silicone, and other high-performance elastomers to deliver trim, weatherstrip, and channel extrusions that meet or exceed automotive industry standards.
