Adhesive Lined Spools

Adhesive-Lined Heat Shrink Tubing – Spools (Dual-Wall Polyolefin)

For high-volume wiring jobs, harness builds, and professional installations, ElecDirect’s adhesive-lined heat shrink tubing on spools offers dual-wall polyolefin performance with spool-level flexibility. This is dual-layer tubing — with a crosslinked outer jacket and a meltable inner adhesive lining — designed to shrink tightly and bond securely when heated, creating a durable, moisture-resistant seal around wires, splices, cables, and connectors.

The 3:1 shrink action ensures a snug seal fit even over irregular shapes, solder joints, or cable breakouts, while the adhesive liner flows to form a water- and moisture-resistant barrier — ideal for automotive, marine, industrial, outdoor, or environmental-exposure wiring.

Supplied on spools, this adhesive-lined tubing gives you the freedom to cut the exact length you need — making it excellent for harness production, long cable runs, maintenance shops, or any job that requires variable lengths and efficient inventory.
