Silco™ End Seal Wrap

Silco™ End Seal Wrap is a self-fusing, non-adhesive silicone elastomer tape manufactured from proprietary, specially formulated silicone rubber that provides heat resistance up to 500°F (260°C). This end seal wrap is primarily used to enclose the ends of firesleeves when installed over hoses to provide a uniform, finished look to assemblies. Moisture-resistant and flexible, it fits smoothly around uneven surfaces and interruptions like hose fittings and instantly adheres to itself with complete, inseparable bonding after 24 hours. Our end seal wrap can also be used in a variety of insulating, repairing, and sealing applications that benefit from its self-adhering, moisture-resistant characteristics.
