Ancor Battery Cable Adhesive Lined Heavy Wall Battery Cable Tubing (BCT) - 3/4" x 6" - Yellow - 3 Pieces

Ancor Battery Cable Adhesive Lined Heavy Wall Battery Cable Tubing (BCT) in 3/4" x 6" yellow offers marine electricians and boat owners a reliable solution for insulating and protecting battery cable connections in harsh saltwater and freshwater environments. Whether you're rewiring a center console, restoring a vintage cabin cruiser, or upgrading electrical systems on a commercial fishing vessel, this heat-shrink tubing prevents corrosion, shorts, and accidental contact that can disable a boat or create dangerous fire hazards at sea.

The adhesive-lined construction provides a watertight seal that bonds permanently to cable insulation when heated, eliminating the need for additional sealants or taping. With a 3:1 shrink ratio, these tubes compress from their original diameter to one-third the size when exposed to 257°F (125°C) heat, creating a tight, uniform jacket around even irregularly shaped connections. The heavy-wall design resists abrasion from deck hardware, rigging, and engine vibration—critical for systems subject to constant motion and temperature cycling. UL 224 certification ensures these tubes meet strict electrical safety standards for marine and industrial applications.

Each package includes three 6-inch segments, providing enough material for battery bank isolation, alternator connections, and auxiliary power distribution in most small to mid-sized vessels. The bright yellow color aids visibility during maintenance and troubleshooting, allowing crews to quickly identify insulated connections in engine rooms and bilge spaces. Installation requires only a heat gun or shrink-wrap tool—no special tools or crimpers needed. This product is ideal for anglers upgrading trolling motor systems, boaters installing new batteries for auxiliary power, and marine technicians seeking durable, marine-grade cable protection for sale or service inventory.
