Description
Volsun EPDM cold shrink tubes with Mastic are rubber insulating sleeves that are pre-expanded over a removable support mandrel. In use, simply position and then remove the support mandrel, allowing the tube to utilize its radial force to form a tight wrap, serving to provide waterproofing and moisture-proof sealing. They are primarily used for the insulation and sealing of cable joints.
