Make wiring repairs that actually last with this Adhesive-Lined Dual Wall Heat Shrink Tubing — a professional-grade 3:1 shrink ratio tubing with a built-in hot-melt adhesive liner that flows when heated to create a fully sealed, waterproof connection. Whether you're splicing battery cables, sealing nav light wires, or protecting trailer harnesses from spray and salt, this is the heat shrink that does the job right the first time.
Key Features
Dual Wall Adhesive-Lined Construction: Outer polyolefin shell shrinks tight while the inner glue layer melts and flows to fully encapsulate and waterproof the connection.
3:1 Shrink Ratio: Aggressive shrink ratio handles a wide range of wire and connector sizes — fits over bulky butt connectors, ring terminals, and irregular splices.
Truly Waterproof Seal: The adhesive bond creates a moisture-tight, corrosion-blocking barrier — essential for marine, automotive, and outdoor wiring.
Strain Relief & Insulation: Adds mechanical reinforcement to splices and prevents abrasion, vibration damage, and shorts.
Multiple Sizes Available: Choose the diameter that matches your application — from small signal wires to heavy battery cable.
Color Options: Available in a range of colors for circuit identification and color-coded wiring.
Easy to Apply: Slip on, position, and shrink with a heat gun or torch — adhesive activates as the tubing contracts.
Long Shelf Life: Stable polyolefin material stores well in the toolbox or shop drawer.
