The ATUM-40/13-0-STK is a Heat-shrinkable Tubing made of adhesive-lined polyolefin. It is available in 3:1 ratio for connector-to-cable sealing. The adhesive in ATUM tubing bonds to a wide variety of plastics, rubbers and metals, including polyethylene, aluminum, steel and copper. Environmentally seals and protects a wide variety of electrical applications, including back-end-connector sealing, breakouts. High expansion ratio makes it possible to repair most damaged cable jackets without removing connectors.
