BuyHeatShrink 1-1/4" Polyolefin Heat Shrink Tubing — 2:1 Shrink Ratio, 50 ft Spool, Black

Durable BuyHeatShrink polyolefin tubing with a 1-1/4" nominal diameter and a 2:1 shrink ratio. Supplied on a 50 feet spool in black, this heat-shrink sleeve provides reliable protection for wire joints, cable bundles and connection points. Heat application causes consistent reduction to half the original diameter for a tight, insulating fit. Easy to trim and install with a heat gun or similar heat source, it’s ideal for electrical insulation, strain relief and abrasion resistance.
