Product Description

4:1 Heatshrink

4:1 Polyolefin Heatshrink Tubing

Our 4:1 over-expanded flexible, flame retardant heat shrinkable polyolefin tubing is used for special circumstances such as jacket retrofitting or repair and electrical insulation of wire assemblies with oversize components or connectors.
The over-expanded product configuration easily fits over the end of a connector, and shrinks down to 25% of its original diameter to fit snugly over the wires.


DIAMETER: 1 1/4"

SHRINK TEMP: 194°F (90°C)



STEP ONE: Measure the Shrinkflex® 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® 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® 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.
