Ancor Adhesive Lined Heat Shrink Tubing (ALT) - 1" x 48" - 1-Pack - Red

Ancor Adhesive Lined Heat Shrink Tubing (ALT) in 1-inch diameter by 48-inch length is a heavy-duty electrical protection solution purpose-built for marine wiring, automotive harnesses, and tactical equipment repair. This red heat shrink tubing shrinks down to 5/16-inch diameter and accommodates wire gauges from 2 to 4/0 AWG, making it suitable for high-amperage applications where standard PVC tubing fails under salt spray, UV exposure, or thermal stress.

The tubing is constructed from cross-linked polyolefin material, which offers superior tensile strength and flame resistance compared to PVC alternatives. The heat-activated adhesive lining creates an impervious seal against saltwater intrusion, oil contamination, acids, and prolonged sunlight exposure—critical for offshore vessels, emergency response gear, and field equipment operating in harsh environments. The adhesive also provides mechanical strain relief at connection points, reducing fatigue failure in high-vibration applications.

Operators and technicians rely on ALT tubing for splice protection in marine electrical systems, battery terminal sealing, connector weatherproofing, and equipment cable management where moisture resistance is non-negotiable. The 48-inch length accommodates multiple splices or longer cable runs without requiring multiple pieces. This single-pack format is ideal for inventory stocking or field repair kits where compact storage is essential. Ancor's adhesive-lined heat shrink tubing is trusted across commercial marine, military, and industrial sectors for applications where standard insulation doesn't meet performance requirements.
