Made from high-temperature SiliconSeal, the gasket remains flexible and effective in extreme conditions from -58°F to 450°F. It is self-extinguishing, non-toxic, and resistant to sunlight, ozone, UV rays, fungus, and mildew. The self-adhesive backing allows quick installation on the top and sides of door frames, and its excellent compression ensures smooth door operation without compromising the seal.
