Use Heat Shrink End Caps to easily form a pressure-tight seal at the ends of power and communications cables. Our end caps feature heavy walls, adhesive lining, high voltage rating, and may be applied quickly and easily using a heat gun or flameless torch. These end caps shrink to fit and seal the exposed termination point of your cables, wires, tubes, pipes, etc and help to prevent corrosion, moisture, and chemical damage as well as abrasion. Use adhesive-lined end caps to create a truly watertight seal. The adhesive lining is activated with heat, and the cap then bonds with the wire/cable enclosure as it cools—creating for a tight seal. These heat shrink end caps are available in many sizes to suit common needs. Practical applications for heat shrink end caps include fiber-optic cable, electrical wire sealing, automotive, generators, and aerospace engineering. Our end caps have high di-electric insulating and sealing properties.
