White Polyolefin Heat Shrink Tubing 3/8" (3:1) - 250 feet/spool

White polyolefin heat shrink tubing with a 3/8" nominal diameter and a 3:1 shrink ratio, supplied on a 250 feet/spool. When heated it reduces to roughly one-third of its original inner diameter, forming a snug insulating sleeve for wires, terminals and cable connections. Simple to cut and apply—use a heat source to achieve a neat, protective fit. Ideal for electrical, automotive and general-purpose wiring where reliable insulation and strain relief are needed.
