This heat resistant wire sleeve is a heavy duty tube-shaped heat guard product designed to protect sensitive components in environments with excessive ambient temperatures and direct heat. The material is a specially formulated Heatshield Products fibrous thermal barrier weave made from volcanic rock. The basalt fiber allows Lava Tube to protect components from a  continuous temperature of 1,200 degrees Fahrenheit and intermittent temperatures of 2,000 degrees Fahrenheit. This makes Lava Tube an ideal and superior alternative to silicon-based thermal barrier heat sleeves in applications above 500 degrees Fahrenheit. Lava Tube is also extremely durable against abrasions and chemical exposure.

Fuel Line Heat Sleeve & Heat Resistant Wire Loom

Lava™ Tube can shield fuel lines from heat damage and act as a heat sleeve for wire looms. By installing a heat shield sleeve to protect fuel lines, you can reduce the risk of fuel vaporization and any subsequent engine performance issues that might arise as a result. Furthermore, installing a Lava Tube over a wire loom can prevent excessive heat from causing wire insulation degradation and melting, short-circuits, and potentially even fires.

Lava™ Tube shield has been designed with a special hook-and-loop fastener system so that it can be installed without the need for disassembling components or removing lines and hoses. The Lava Tube high-temperature wire sleeve is available in four diameters ranging from 1/2-inch to 1 1/2-inches, and either 3-foot- or 10-foot-long rolls. It can be easily cut to length, but we strongly recommend using heat shield tape or heat shrink on the end to reduce fraying.
