3:1 adhesive lined heat shrink shrinks to 1/3 its original diameter at a temperature of 100C. The inner layer is a hot melt glue which melts when heated and then solidifies when cooled, forming a water proof barrier protecting the connector and/or the wire underneath. It also makes the tubing stick to the wire, creating a strong bond.
