Raychem ATUM Tubing 4:1

4:1 High-Shrink-Ratio, Adhesive-Lined Polyolefin Tubing

Environmentally seals and protects various electrical applications, including back-end connector sealing, breakouts, and connector-to-cable transitions. In addition, a high expansion ratio makes it possible to repair most damaged cable jackets without removing connectors.

The installed tubing provides rugged protection against abrasion, vibration, and flexing. Only a few sizes of ATUM tubing can accommodate a wide range of applications.
