High silica sleeve

High silica  sleeve is a braided silica sleeve, constructed from a 96% pure SiO2 silica fiber, suitable for continuous use at 1800°F (982℃), and able to withstand short term exposure up to 3000°F (1650℃). Silica Braided Sleeve is ideal for protection of delicate components and personnel from exposure to high temperature exhausts and pipes. This Silica Braided Sleeve cuts easily with scissors or shears and expands to allow easy installation over water cooling hoses, hydraulic hoses, and electrical cables. Also provides great insulation for exhaust systems.
