Introduction:
EPDM Cold Shrink Tubes are a series of open-ended, tubular rubber sleeves, which are factory expanded and assembled onto a removable core. They are supplied for field installation in this pre stretched condition. The core is removed after the tube has been positioned for installation over an in-line connection terminal link allowing the tube to shrink and form a waterproof seal. The insulating tube is made of EPDM rubber which contains no chlorides or sulphurs.
