Tronic Red Heat Shrinkable Tubing 20mm x 100m

Our review

This is a 100-metre reel of red heat shrinkable tubing from Tronic, with a 20mm diameter. It is used to insulate, protect and bundle electrical wires, cables and components, so it suits electricians, technicians, panel builders and anyone doing regular wiring work who wants one colour and one size on hand rather than mixed packs. Before buying, confirm that 20mm is the expanded diameter you need and that the tubing will shrink down far enough to grip your cable or joint tightly, since shrink ratios are not stated here. Also check the wall thickness and whether the red colour matters for your colour-coding. Compared with assorted multi-size kits, a single 100m reel is better value if 20mm is your common size, but less flexible if you work across many diameters. Available on Sokonia.
