Ancor 1" x 48" Yellow Heat Shrink Tubing

The Ancor 1" x 48" Yellow Heat Shrink Tubing is a cross-linked polyolefin cable protection solution designed for marine, automotive, and industrial electrical applications. This tubing is engineered to withstand harsh environmental conditions where standard PVC alternatives fail, making it the go-to choice for professionals who demand durability and reliability in corrosive environments. Whether you're bundling wires on a boat, securing connectors in engine bays, or protecting cables from UV exposure and chemical degradation, this 48-inch length provides ample coverage for most single-run applications.

Manufactured from cross-linked polyolefin material, the Ancor heat shrink tubing offers superior strength and fire resistance compared to conventional PVC tubing, which can burn and degrade under thermal stress. The 1-inch diameter accommodates larger wire bundles and connector housings with ease. What sets this product apart is its heat-activated adhesive lining, which creates an impervious seal that protects against salt water intrusion, oil penetration, acids, and harmful UV radiation—critical for marine and outdoor installations. The adhesive bond forms permanently when heated, ensuring long-term environmental protection without additional sealants or tape.

This tubing is ideal for boat builders, marine technicians, automotive restoration specialists, and anyone working in saltwater or chemically aggressive environments. The yellow color provides high visibility during installation and maintenance, reducing the risk of accidentally damaging cables during future work. Installation requires only a heat source (heat gun or shrink tool) to activate the adhesive lining and compress the tubing around your cable bundle or connector. The 48-inch length is sufficient for single connections, transition points, or custom cutting to match specific routing requirements in tight spaces.
