Yellow 1" Polyolefin Heat-Shrink Tubing — 3:1 Shrink Ratio, 100 ft Spool

Bright yellow polyolefin heat-shrink tubing with a 1" expanded diameter and a 3:1 shrink ratio, supplied on a 100 feet spool. When heat is applied, the tubing reduces to roughly one-third of its expanded size to form a tight, protective sleeve over wires, splices and terminations. Ideal for insulating, bundling and color-coding electrical connections in general-purpose applications. Easy to use: slide over the joint and apply controlled heat until the tubing conforms. Packaged as a single 100 ft spool in yellow.
