Jaycar 20mm Black Heatshrink Tubing – Flame-Resistant Polyolefin, 50% Shrink Ratio

You've got a thick cable run with exposed ends or a joint that needs proper insulation, and you don't want to wait a week for a national chain to ship a tube of shrink. This 20mm black heatshrink is on the shelf, ready to slide over your wire and lock in tight. Made from flame-resistant polyolefin and rated to 125°C under UL224 E180908, it shrinks to half its original diameter for a snug, protective seal. Pop it over the joint, run a heatgun, hairdryer, or even a gas burner along the length, and you're done. No epoxy, no waiting, no mess. Grab the size that sits comfortably over your conductor, shrink it on, and get back to whatever else is on your list
