Ancor 1" x 48" Red Heat Shrink Tubing

The Ancor 1" x 48" Red Heat Shrink Tubing is a professional-grade electrical protection solution designed for marine, automotive, and industrial wiring applications. This cross-linked polyolefin tubing provides durable insulation and environmental sealing for wire bundles, connections, and terminals that demand corrosion resistance and long-term reliability. Whether you're rewiring a boat, restoring a vehicle, or assembling industrial harnesses, this heat shrink tubing protects against salt water intrusion, oil contamination, and UV exposure in demanding environments.

Manufactured by Ancor, a trusted brand in marine-grade electrical components, this tubing is constructed from cross-linked polyolefin material—a superior alternative to PVC that resists burning and degradation under stress or heat exposure. The integrated heat-activated adhesive lining creates an impervious seal that blocks salt water, petroleum products, acids, and harmful UV rays, extending the service life of wrapped connections significantly. Simply slide the tubing over your wire, connector, or joint, apply moderate heat with a heat gun or hair dryer, and the adhesive activates to form a waterproof, airtight bond that won't degrade or separate over time.

The 1-inch diameter and 48-inch length make this tubing ideal for larger wire bundles, cable looms, and substantial connector protection in marine engine compartments, bilge areas, and external wiring runs. Professionals in marine repair, automotive restoration, and industrial maintenance rely on Ancor heat shrink tubing for its proven durability and ease of installation. This single piece can be cut to custom lengths for multiple applications, making it a cost-effective choice for workshop inventory and field repair kits.
