You've got a slightly thicker cable and that standard 5mm tube just won't seat right over the joint. This 6.0mm red heatshrink gives you the extra headroom to wrap a bulkier splice without forcing it. Flame-resistant polyolefin, UL224 E180908 rated to 125°C, shrinks to half its size and grips firm. Heatgun, hairdryer, gas burner — whatever's on the bench works. Sorted in seconds
