Engineered with 19 oz high-temperature glass fiber insulation bonded to an aluminized outer layer, this sleeving reflects damaging radiant heat while remaining pliable enough for tight bends and complex routing.

  • Chemical Resistance: Protects internal lines from oil spills, chemicals, dirt, grease, and road grime.
  • Simple Installation: Designed to slide over lines once unhooked; material can be easily trimmed to length with standard shears.

Technical Specifications:

  • Length: 3 feet
  • Material: Aluminized high-temperature glass fiber
