We Guarantee to Have the Best Price

What's special about this expandable fiberglass braided sleeving?

  • Resin coated fiberglass construction provides excellent durability and high temperature resistance for protecting cables, wires, and hoses used in extremely hot environments, such as engine manifolds, exhaust systems, or in boiler/furnace rooms
  • Capable of withstanding fire and temperatures up 1,200° F without burning, melting, or becoming brittle
  • Tightly woven fibers provide cables and hoses with a high degree of protection from abrasion or damaging chemicals
  • Click for More Features
RoHS Compliant

High temperatures, fire, and machine oils can pose a real threat to the cables, wires, and hoses that are necessary to keep hardworking engines and components up and running. Adding quality fiberglass braided sleeving products to exposed cables and hoses adds a wide range of benefits, such as: cable management, increased life, better performance, and long-lasting protection from the outside elements. Insultherm™ Resin Coated Fiberglass Braided Sleeving provides excellent continuous heat resistance up to 1,200° F (640° C) for exposed cables/hoses, while maintaining tight structural strength under constant vibration, mechanical stress, abrasion, and fluctuating temperatures.
