Exhaust Heat Wrap Overview

Davlyn Basalt Tape, Sleeve, and Rope provide high-performance solutions for the more extreme temperature applications. Made from volcanic rock, our basalt products are environmentally friendly, 100% recyclable, and non-hazardous.

Basalt Exhaust Tape

Basalt Exhaust Tape is constructed from high-quality basalt fibers woven into a 2-inch tape. Recommended for a continuous operating temperature of 1382°F (750°C), Basalt Tape provides an excellent exhaust heat shield. When applied as an exhaust heat wrap, the tape provides thermal insulation and radiant heat protection.

Basalt Exhaust Sleeves

Knit Basalt Sleeves are constructed with basalt fiber yarns knit into a heavy-wall sleeve to provide an exceptional combination of enhanced heat resistance, thermal performance, and durability when compared to typical fiberglass sleeve products. When installed on diesel truck exhaust tubes and pipes as an exhaust wrap, our Basalt Sleeve facilitates an increase in the efficiency of a vehicle’s emission control system through the retention of high temperatures as gases flow through the exhaust system.

Basalt Exhaust Rope

Knit Basalt Rope products are manufactured from the same high-quality basalt yarns as our sleeves for maximum thermal protection in extreme heat applications.

Superior Exhaust Wrap for Heat Protection

Davlyn Basalt Tape combines thermal performance and exceptional aesthetics to provide an ideal car, truck, and motorcycle exhaust wrap. Exhaust tape increases the efficiency of an exhaust system, providing a performance boost, and reduces radiant heat to surrounding components and passengers. Basalt exhaust tape is a more durable material than fiberglass or carbon fiber tapes.

Extreme Heat Applications

The knit basalt sleeve has a durable, light-weight construction that provides excellent flexibility for easier installation around tight bends and over fittings, couplings and other obstructions. The dense single-wall design provides optimal coverage and minimizes snagging during installation. In addition, the knit construction allows neat, easy field-cutting without specialized tools. Knit basalt sleeve is the ultimate solution for extreme heat applications.

All of the basalt products are recommended for operating temperatures up to 1382°F (750°C). Used on hot pipes, they retain heat within the wrap and reduce radiant heat. Basalt Tape and Sleeves can also be used to keep parts cool, protecting components from surrounding heat in engine, machinery and industrial applications.
