HOW TO INSTALL SHRINK TUBING

STEP ONE:Measure the Shrinkflex® shrink tubing to length and cut with a scissor. The thickness of your bundle, as well as the desired final appearance, will determine the length of the tubing you cut. Generally, a piece 1 1/2” - 2” long will accommodate almost any need. Single wires, or smaller bundles, require shorter pieces.

STEP TWO:Slip the Shrinkflex® heat shrink tubing over the bundle and position it so that both the sleeved and unsleeved portions are sufficiently covered. Notice the small pieces of tubing in- stalled on single wires as part of a color coding system. If your project requires multiple operations, always work up from the smallest to the largest bundle.

STEP THREE:Gently apply heat to Shrinkflex® heat shrink tubing from a heat gun, hair dryer or torch with an appropriate attachment. Keep the heat source far enough away so that hot metal or direct flame does not come in contact with the tubing, wires or sleeving. Move the heat around the bundle to prevent damaging the sleeving and to ensure that all areas of the tubing have been shrunk. Once cooled, your installation is complete.
