3:1 Heat Shrink Tubing Polyolefin - Electriduct

3:1 Polyolefin heat shrink will shrink down to one third of its nominal diameter, and less than 10% of its length.

The diameter of heat shrink tubing is measured as a round tube, not flat, so make sure that the shrink tubing is larger than what you are covering.

Use the 3 to 1 heat shrink tubing to insulate cables and wires, provide a protective barrier, strengthen cable joints and color code wires.

  • RoHS Compliant
  • UL224 (Standard)
  • 600V Potential Rating
  • 100 Feet Spools- 1/16" to 1-1/2" (may not be continuous, especially in larger sizes)

Attention: Due to the nature of the manufacturing process, same colors may not exactly match between sizes, models and batches. Sizes given are approximate and will vary.
