Dual-Wall Tubing

Dunbar Dual-Wall Tubing is semi-rigid or flexible, high-shrink-ratio, flame-retardant, and heat-shrinkable polyolefin tubes. This tubing comes 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. This dual-wall tubing is UL VW-1 (Jacket only) and is flammable, and it complies with RoHS and REACH. The dual-wall tubing can be used to seal and protect a wide variety of electrical applications, including wire splices, breakouts, and connectors-to-cable transitions.
