Dual-Wall Tubings

Dunbar Dual-Wall Tubings are semi-rigid or flexible, high-shrink-ratio, flame-retardant, and heat-shrinkable polyolefin tubes. These tubings come with an adhesive lining that forms an environmental seal that helps protect against moisture. The dual-wall tubing offers excellent electrical properties and high resistance to abrasion, chemicals, and oils. These dual-wall tubings are UL VW-1 (Jacket only) flammable and comply with RoHS and REACH. The dual-wall tubings can be used to seal and protect a wide variety of electrical applications, including wire splices, breakouts, and connectors-to-cable transitions.
