Black 1/2" Pre-Flattened Polyolefin Heat-Shrink Tubing — 3:1 Shrink Ratio

Black polyolefin heat-shrink tubing, pre-flattened and sized at 1/2" with a 3:1 shrink ratio. Designed to shrink to one-third of its original diameter when heated, this tubing forms a snug protective sleeve for wire splices, terminations and repairs. The pre-flattened profile simplifies handling and cutting, while the polyolefin material offers reliable insulation and abrasion protection.
