For decades now, the effective SUPERTHERM® design has stopped valuable & vulnerable cables and lines from melting under intense heat conditions. While encased in our aerospace grade high temperature pipe lagging, your fuel lines, hydraulic hoses, electrical cables, and fiber optics will be protected against constant heat of up to 260°C, and molten splash temperatures of up to 1200°C.The SUPERTHERM® fireproof sleeve is made using braided fiberglass, giving it great flexibility and exceptional insulating prowess. Top this design off with an outer layer coating of premium-grade silicone to avoid abrasion, and it's easy to see why this fire sleeve is just so effective.
