Woven Fabric Heat Shrink
Looking for long-term solutions that prevent cable damage?
Even the most durable cable jacketing materials (e.g. Polyurethane) can eventually fail under harsh conditions, leading to costly downtime and repair expenses. Proactively addressing cable protection can save both time and money in the long run.


Flexible Heat-Shrinkable Cable Protection
Dunbar’s ArmorFlex® WFHS-221 is a woven fabric heat-shrink tubing designed to mechanically protect cables, wire harnesses, and other components from abrasion, cutting, and fluids. Its polyester/polyolefin woven construction offers a 2:1 shrink ratio, adhering snugly to cables to provide enhanced protection while maintaining flexibility.
ArmorFlex significantly extends the operating life of installed cables by offering superior physical protection. Its heat-shrinkable and flexible nature ensures that it moves with the cable, preserving flexibility and bend radius.
