Black Polyolefin Heat-Shrink Tubing — 3/8" (3:1) — 250 ft Spool

Durable black polyolefin heat-shrink tubing, supplied on a 250-foot spool. This 3/8" diameter tubing features a 3:1 shrink ratio, allowing it to contract to approximately one-third of its original size for a snug fit over wires, splices and connectors. Ideal for insulating electrical connections, providing strain relief and protecting against abrasion, the tubing is flexible and easy to cut and apply with a heat source. Sold per spool (250 feet), color: black.
