Marine Heat Shrink Tubing for Boats and Marine Crafts

BuyHeatShrink.com ships a complete line of Boat and Marine Craft heat shrink tubing products for every marine application. Our polyolefin Heat Shrink Tube comes in all popular specifications, including adhesive and non-adhesive options. Both options are flame retardant, and well suited to protect wiring from air moisture and environmental elements which cause corrosion. BuyHeatShrink.com Heat Shrink Tubing enhances insulation, resists abrasion, and relieves strain on exposed wiring for marine craft of all shapes and sizes.

Heavy-duty, adhesive-lined shrink tubing engineered to withstand continuous saltwater exposure, vibration, and harsh marine environments. Build watertight, corrosion-proof electrical connections that meet strict ABYC and USCG safety standards.

Eliminating Corrosion in Marine Wire Harnesses & Splices

Electrical failure is one of the leading causes of breakdowns at sea. Standard single-wall tubing is completely insufficient for marine environments because it allows moisture to wick up the copper strands via capillary action, accelerating corrosion. Our marine-grade dual-wall heat shrink features an inner layer of specialized adhesive glue that melts entirely during the shrinking process. This inner liner encapsulates the wire splice or terminal lug, creating a rugged, hermetic seal that completely blocks out salt water, fuel, oil, and battery acid. Formulated for maximum flexibility and high shrink ratios (3:1 and 4:1), it easily slides over large connector plugs and shrinks down tightly onto small wires without splitting.
