Ancor Marine Grade Electrical Adhesive Lined Heat Shrink Tubing

Ancor adhesive-lined heat shrink tubing (ALT) is a marine-grade solution for electrical insulation, wire management and environmental sealing. Constructed from cross-linked polyolefin, the tubing is stronger than PVC and resists burning; a heat-activated adhesive lining provides an impervious seal to salt water, oil, acids and sunlight while offering strain relief. The product family features a highest shrink ratio that reduces tubing to one-third of its original diameter (3:1), with typical shrink temperature ~257°F (125°C) and an operating temperature range from -40°C to 110°C. Tubing in this family is UL 224 recognized and covers wire gauge ranges shown across variants (examples span roughly from 20 AWG up to 4/0 AWG). Offered in multiple diameters, lengths, colors and pack sizes, these tubes are suited for marine, boating, automotive, industrial and general electrical wiring applications where a durable, waterproof seal and mechanical protection are required.
