3:1 Polyolefin Heat Shrink Tubing

3:1 Polyolefin Heat Shrink Tubing
3:1 Heat Shrink Tubing | Polyolefin Heat Shrink  

3:1 Polyolefin heat shrink will shrink down to one third of its nominal diameter, and reduce 10% of its pre-shrunk 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)

Mr
Exactly what I was needing to repair the crumbling cable shield on my old MacBook Pro charging cable. Don’t remember who I talked to, but he suggested the 3:1 and it worked out great! Thanks for the help.

We use this as the final element on our patented pickleball paddle, the Picklesword. It gives it the finished look and feel as well as being a seal between the handle and blade. Will for sure keep ordering this. www.picklesword.com
