HEAT SHRINK CAPS feature a closed end design that seals cable ends and unused connections, creating a strong and permanent environmental seal. With a continuous temperature limit of -40°F to 212°F and a shrink temperature of 257°F, these caps provide excellent resistance to weathering and moisture. The large capacity allows for easy insertion of wires, while the special adhesive lining ensures a positive seal on irregular cable sheaths. Suitable for various applications including connector ends and power cables, installation is quick and straightforward.
