2-Pk. Heat Shrink Tubing, 3/4 - 3/8 X 4-In.

Gardner Bender heat shrink tubing provides reliable protection and insulation for electrical wires, cables, and connections in automotive, marine, and general electrical applications. This 2-pack of dual-size tubing (3/4 inch to 3/8 inch diameter) contracts uniformly when heated to form a tight, moisture-proof seal that resists abrasion, chemicals, and common fluids. The non-adhesive polyolefin construction eliminates the need for additional adhesives while delivering professional-grade results on repairs, splices, terminations, and protective wraps.

Whether you're repairing vehicle harnesses, sealing rope ends, adding grip to tool handles, or organizing a DIY electronics project, this heat shrink tubing provides a clean, durable barrier that enhances both safety and performance. The flexible taper design accommodates a range of conductor diameters, streamlining installation and reducing the need for multiple tubing sizes.
