Jaycar Heatshrink Tubing with Glue Lining 4:1 – 8.0mm | Water & Dust Resistant Seal

You've got a splice that's been rattling around in a loom for months, and the first real rain is going to find it. This is the fix. The Jaycar 8.0mm heatshrink tube has a heat-sensitive glue lining on the internal wall. You slip it over the joint, apply heat with a standard heat gun, and the glue melts into a solid, water and dust resistant seal. 4:1 shrink ratio means it grips tight without looking like a band-aid. Part of a range from 4.0mm to 24mm (WH-5640 through WH-5646), so you can match the tube to whatever cable you're sealing. Grab the right size, heat it on, and that joint's done for good
