Yellow 3/16" 3:1 Polyolefin Heat Shrink Tubing - 500 ft Spool

Yellow polyolefin heat shrink tubing with a 3/16" nominal diameter and a 3:1 shrink ratio, supplied on a 500 feet spool. The 3:1 ratio allows the tubing to recover to approximately one-third of its original diameter when heat is applied, forming a snug, protective sleeve. Polyolefin construction delivers dependable electrical insulation, flexibility, and resistance to abrasion and common chemicals, making this tubing suitable for wire harnessing, cable repair, color-coding, strain relief, and general electrical protection. Use a heat gun or other controlled heat source to shrink the tubing until it fully recovers. Each spool contains 500 feet to support large jobs and multiple repairs.
