Ancor Battery Cable Adhesive Lined Heavy Wall Battery Cable Tubing (BCT) - 1" x 3" - Yellow - 2 Pieces

The Ancor Battery Cable Adhesive Lined Heavy Wall Battery Cable Tubing (BCT) in 1" x 3" yellow is an essential protective solution for marine electrical systems. After years on the water, any experienced boater knows that battery cable corrosion and abrasion are silent killers of reliable power distribution. This two-piece tubing set safeguards your boat's most critical electrical connections from moisture, salt spray, and mechanical wear—the three forces that degrade unprotected cables in harsh marine environments.

Built to Ancor's UL 224 standard, this heavy-wall tubing features an adhesive-lined interior that bonds securely to cables without additional fasteners or glues. The 3:1 shrink ratio ensures a tight, uniform fit over 1-inch diameter battery cables, and the material activates at 257°F (125°C)—a controlled shrink temperature that prevents heat damage to copper or tinned conductors. The bright yellow color serves dual purposes: it meets marine safety visibility standards and makes cable identification quick during maintenance or troubleshooting in engine compartments or bilges.

This tubing is ideal for anglers and cruisers who run high-draw systems—trolling motors, large battery banks, inverters, or dual-engine platforms where cable integrity directly impacts safety and uptime. Each 3-inch piece covers one connection point; the two-piece pack is typical for a single main battery-to-bus run or two starter cable terminals. Installation is straightforward: slide tubing over the cable, apply controlled heat (heat gun recommended), and the adhesive seals the tubing permanently against the conductor. Marine electricians and DIY boaters alike rely on Ancor BCT for lasting protection in saltwater, freshwater, and demanding offshore conditions.
