Silicaflex™ Firesleeve

Braided 96% pure silica fiber, the health conscious alternative to asbestos and ceramic sleeves and wraps.



Outstanding durability and flexibility

Silicaflex™ sleeves set the standard for flexibility and minimum lineal shrinkage under high heat conditions. Durability is further enhanced with a proprietary hydro-carbon coating, giving Silicaflex firesleeves unmatched abrasion resistance and tensile strength.

Excellent high-heat performance

Silicaflex™ is a braided silica sleeve, constructed from a 96% pure SiO2 silica fiber, suitable for continuous use at 1800°F (982°C), and able to withstand short term exposure up to 3000°F (1650°C).

Silicaflex™ sleeves can be combined with other low cost sleeve products to increase insulation values or abrasion resistance for the most demanding applications.
