3M™ Cold Shrink Insulators are open-ended, tubular, EPDM rubber sleeves which are factory expanded and assembled onto a removable core. The core is removed after the tube has been positioned for installation over an inline connection, terminal lug, etc., allowing the tube to shrink and form a water-resistant seal.

3M™ Cold Shrink Insulators are designed using a unique cold shrink delivery system. They are supplied prestretched on a removable core for efficiency and ease of installation. Removal of the core after positioning allows the product to shrink into position forming a moisture-tight seal. The live memory action of the specially formulated material ensures a permanent, durable environmental seal and insulation.

Suggested Applications

Primary electrical insulation for all solid dielectric (rubber and plastic) up to 1kV
Direct burial and submersible applications
Insulate tape shield, wire shield or UniShield® cable
Environmental sealing for communications and other non-electrical applications
Sheath repairs
Physical protection and moisture sealing for air-insulated connectors and lugs such as spacer cable and lug connections to bus bar
