12 Gauge-2 Gauge Insultherm Ultra-Flex Fiberglass Loom - 100 Feet

Ultra-Flex Fiberglass Loom

Ultra-Flex Fiberglass Loom Logo

The Ultra-Flex high-temp sleeving is an ideal protection solution for wires and hoses that are exposed to the heat generated from high perfromance engine and exhaust components. The absence of an acrylic coating or binder makes the sleeve flexible and versatile. The sleeve will stay flexible in low temperatures, and can follow curves and contours without binding. The sleeving is typically used in high-temp (up to 1,200°F), low voltage applications.


  • Made from continuous filament, E-Type glass.
  • Resists abrasion, vibration, and mechanical stress.
  • Cuts cleanly with our Heavy Duty Serrated Scissors.
  • Expands slightly to slide easily over wires.
  • UL Recognized, VW-1 Flammability Rating.
  • Operating Temperature Range: -70°C to 650°C (-94°F to 1,202°F).
  • Available in Natural Color.
