This D-shaped rubber seal is constructed from high density EPDM material that stays intact without freezing or cracking under extreme temperature conditions. It measures 1 inch in width and 1.1 inches in height, with a built-in self-adhesive backing that delivers long lasting strong adhesion to smooth clean surfaces. The strip effectively improves overall leak tightness, blocks outside noise, reduces unwanted vibration, and offers reliable performance against water, wind, UV rays, scratches and harsh weather elements. Its hollow flexible structure features excellent resilience to fill various gaps and cracks, and absorb impact to protect adjacent surfaces. It fits a wide range of application scenarios including residential doors, windows, cabinets, vehicles, boats and recreational facilities, and requires no specialized tools or professional experience for full installation.
