Silicone Cold Shrink Wrap 25-70mm


Cold shrink wrap is a specially formulated tubular rubber sleeve pre-expanded on a removable plastic cylinder for easy installation. It does not require heat to shrink, you just need to pull the plastic cord, and then the silicone rubber tubing will shrink rapidly and grip around the cable tightly, which will provide a reliable, long-term sealing and protection to the connector.

Features

» Easy and quick installation

» Does not require any tools or heat

» Provides good thermal stability

» Accommodates a broad range of cable sizes

» Excellent tear resistant

» UV and ozone aging resistant

Note: In certain applications, a foam tape will be needed for smaller cable diameter that cannot be covered with the tube range, the foam tape is used to increase the smaller cable diameter and assure the sealing of clod shrink tube.
