EPDM Cold Shrink Tube

ECST series 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 lug, etc., allowing the tube to shrink and form a waterproof seal. The insulating tube is made of EPDM rubber, which contains no chlorides or sulphur.
