Jaycar 2:1 Heatshrink Tubing 2.5mm ID x 5m – Black | WH5681

You've got a spliced joint chafing against a chassis rail, or a thin cable run that's lost its insulation and you can't risk it arcing in the van. This 5m box of 2.5mm ID heatshrink fixes that in under a minute per joint. Cut a piece, slide it over, hit it with a heatgun — done. No solder, no tape peeling off in the heat. VW-1 flammability rated, RoHS and UL224 approved. Stacks flat in your toolbox drawer or on the van shelf at 49 x 177 x 165mm. Five metres is enough for a full day of small-joint work without running back to the shop
