Heatshield Products Lava Hot Rod Sleeves

Prevent vapor lock and shift cables from melting with Lava hot rod sleeves from Heatshield Products. The heat shields for fuel lines combine the best of two worlds, the flexibility of a rugged hot rod sleeve with the strength of lava rock fiber. Lava fiber is naturally acid, chemical, brake fluid, and chemical-resistant. Additionally, the fiber is 25 percent stronger than fiberglass and is abrasion-resistant. The special braid of these tube heat shield sleeves allows them to have an expandable inside diameter up to 15 percent. To expand the inside diameter, shorten the length or bunch up the Lava hot rod sleeve to allow it to slide on over fittings and terminals. Once over, expand or stretch the length to tighten the sleeve onto the line or hose. To cut, use a sharp knife or pair of scissors. Each kit includes four heat shrinks to seal the ends of the oil line heat shield sleeve to the cable, tube, or hose it is protecting. Remember a loose-fitting heat shield sleeve is okay if the ends are sealed to prevent heat from getting trapped between the sleeve and the component it is protecting. The 10 ft. long sleeves are available in diameters ranging from 1/4 in. to 1.5 in. Additional details: * Heat shield loom and Hot Rod Sleeves shield harnesses and fuel lines even in harsh environments. They can reduce radiant heat damage and prevent vital fluids such as fuel from overheating. * Rated for 1,100 degrees F * Maximum ambient temperature: 2,000 degrees F * Lava fiber resists chemicals, oil, fuels, and even acid * Heat shield protection for: -- Fuel lines -- Brake lines -- Transmission lines -- Oil lines -- Turbo lines -- Harnesses
