3M 8420 Series 49.3mm x 152mm Black Cold Shrink Tubing 8428-6

This is a 3M 8420 Series 49.3mm x 152mm Black Cold Shrink Tubing 8428-6. The 3M 8420 series black 152mm cold shrink connector insulator is an open-ended, tubular, rubber sleeve. It is factory expanded and assembled onto a removable core. The core is removed after the tube is positioned for installation over an inline connection and terminal lug. This allows the tube to shrink and form a water-resistant seal. The insulating tube is made of EPDM rubber, which contains no chlorides or sulphurs. It is available in diameter sizes that cover a range of cable up to 1000V for copper and aluminum conductors.
