Upgrade your wiring projects with this dual wall heat shrink tubing featuring a built-in hot melt adhesive liner. When heated, the outer polyolefin sleeve shrinks at a 4:1 ratio while the inner glue melts and flows into gaps, creating a sealed, waterproof and strain-relieved connection that resists moisture, dust and vibration.
Ideal for automotive harnesses, marine wiring, home electrical repairs, RC models and DIY electronics, this tubing protects splices, terminals and cable joints with a professional, long-lasting finish. The 4:1 shrink ratio lets one sleeve cover a wide range of cable diameters, so you can keep fewer sizes on hand.
