Product Overview

Silco™ End Seal Wrap is a self-fusing, non-adhesive silicone elastomer tape that is primarily used to enclose the ends of firesleeve when installed over a hose and provide a uniform, “finished” look to the assembly. End Seal Wrap can also be used for a wide variety of insulating, repairing and sealing applications that benefit from its self-adhering, moisture resistant characteristics.
