3M’s cold-shrink products are pre-stretched on a removable core so they will shrink to fit to ensure a permanent, durable environmental seal and protection. This helps you reduce the time, labor and cost involved in a variety of electrical cable splicing applications. These kits are applicable for indoor and outdoor installations, including direct burial, aerial and submersible applications. Each kit requires 1 roll of 3M™ Armorcast™ Material. The 3M™ Splice Kit 8420 Series is an EPDM rubber splice for 0-1000 volts. The 3M™ Splice Kit Series 8440 includes insulating sleeves made from a specially formulated high-temperature silicone rubber with an operating temperature range from -67° F (-55° C) to 500° F (260° C).
