Each seal is engineered to match the original profile and mounting groove of your Oldsmobile 98—restoring a tight, quiet seal around your doors, trunk, hatch, and windows.

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.
