DEI Wire Markers Numbered 1-8 (8pc) - Black

DEI numbered wire marker set, eight black Mil-Spec heat-shrink tubes printed 1 through 8 in high-visibility oil- and chemical-resistant white ink, for labeling spark plug / ignition wires. The 3:1 shrink ratio slides over plug-boot ends and shrinks tight to the wire; the thick-wall, flame-retardant tubing handles under-hood heat (operating -67°F to 275°F, 394°F short-duration).
