3M 8429-18 Cold Shrink Connector Insulators
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)

Material Notes: 3M™ Cold Shrink Connector Insulators are open-ended, tubular, 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. The insulating tube is made of EPDM rubber which contains no chlorides or sulfur. Six diameter sizes will cover a range of cable up to 1000 volts for copper and aluminum conductors from 10 AWG through 1000 kcmil.
