3/16" 3:1 Polyolefin Heat Shrink Tubing — 500 ft Spool, White

White polyolefin heat-shrink tubing with a 3/16" nominal diameter and a 3:1 shrink ratio, supplied on a 500-foot spool. This tubing is designed to shrink down to roughly one-third of its original size to form a tight, protective sleeve over wires, splices, terminals and connectors. Polyolefin material provides dependable electrical insulation along with good resistance to abrasion and typical environmental exposure, making it suitable for electronics, automotive, marine and general-purpose cable protection. Flexible and easy to apply with a heat gun, it works well for bundling, color-coding, strain relief and finishing wiring installations.
