Our 3:1 heat shrink tubing is good way to finish the ends of a wiring harness. More versatile than standard 2:1 heat shrink tubing, a 3 to 1 shrink ratio allows you to leave connectors on the wires saving valuable labor time. The added expansion translates to a heavier wall providing added abrasion resistance. We offer several colors, allowing you the freedom to match wire or braided sleeving colors. Our heat shrink tubing is available in bulk reels or "mini" spools.
