Connector Insulator Tubes

3M Electronic Specialty Connector Insulator Tubes are open-ended, tubular, rubber sleeves that are factory-expanded and assembled onto a removable core. The core is removed after the tube has been positioned for installation, allowing the tube to shrink and form a water-resistant seal. Six diameter sizes will cover a range of cable up to 1000V for copper and aluminum conductors from 10AWG through 1000kcmil.
