Medium-Insulated Dual Wall Shrink Tube Spools for Enhanced Protection in Harsh Conditions

Dual Wall Shrink Tube Spools in black, available in 3/8" to 3/4" sizes, are constructed from medium-insulated polyolefin for effective, flame-retardant protection. This dual wall tubing incorporates a modified polyimide adhesive that melts and flows with heat, creating a sealed, encapsulating barrier around components. Designed for outdoor, automotive, and marine environments, this tubing offers robust protection against fluids, moisture, and corrosion, enhancing durability in demanding applications.

Perfect for safeguarding electronic components, wire splices, and connectors, this tubing ensures secure, reliable sealing with a 3:1 shrink ratio for a snug fit around various components. With a shrink temperature of 125°C (257°F) and an operational range from -45°C to 125°C (-49°F to 257°F), it performs dependably in extreme conditions. This tubing is UL listed and RoHS compliant, meeting essential safety and environmental standards for use in critical installations.
