Basalt Sleeves

Basalt Sleeve

Davlyn’s Basalt Sleeve provides 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 1382°F/750°C, Basalt provides an excellent exhaust heat shield. The knitted construction is resistant to most oils, fuels, acids, alkalis and other fluids and allows neat, easy field-cutting without specialized tools.

Made from volcanic rock, our basalt products are environmentally friendly, 100% recyclable, and non-hazardous.
