Basalt Sleeve Overview
Davlyn basalt sleeve, tape, and rope provide high-performance solutions for the more extreme high-temperature applications.
Knitted basalt sleeves are constructed with basalt fiber yarns knitted 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. Recommended for a Continuous Operating Temperature of 1400°F (760°C), basalt sleeve provides an excellent thermal insulation for exhaust systems and radiant heat protection for the surrounding components.
Woven basalt high heat tape and knitted basalt rope products are manufactured from the same high-quality Basalt yarns as our sleeves for maximum thermal protection in extreme heat applications.

Davlyn knitted 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 knitted construction allows neat, easy field-cutting without specialized tools. Knitted basalt sleeve is the ultimate solution for extreme heat applications.
Knitted basalt ropes are designed and manufactured similar to our fiberglass ropes, providing a like range of standard & custom sizes with enhanced temperature and abrasion resistance.The basalt ropes can be made into different shapes like rounded, squared or twisted. These basalt ropes can be coated with different materials for varied applications.
Basalt tapes combine thermal performance and exceptional aesthetics to provide an ideal option for wrapping exhaust manifolds and tubes.
Davlyn basalt sleeve is available in knitted construction in sizes from 1″ (25.4mm) through 6″ (152mm); basalt rope is available in sizes from 1/16″ (1.6mm) through 4″ (102mm); basalt tape is available in 2″ (51mm) width.
