Red Polyolefin Heat Shrink Tubing — 1" Diameter, 3:1 Shrink Ratio, 100 ft Spool

Red polyolefin heat shrink tubing supplied on a 100-foot spool. The tubing has a 1" nominal diameter and a 3:1 shrink ratio, so it reduces to roughly one-third of its original size when heated, creating a tight protective sleeve. It’s intended for insulating wire splices, providing strain relief, bundling cables, and adding color-coding or abrasion protection to harnesses and connectors. Made from flexible polyolefin, this tubing is easy to apply with a heat gun and forms a secure jacket around terminals and joints. Packaged as 100 feet per spool in red.
