Fire sleeve(Pyrojacket) made by Braid bulk glass fiber sleeve and extrudeflexibility Silicone Rubber, it can withstand repeated exposures to moltensteel, molten aluminum and molten glass. The coating of our proprietaryiron oxide red silicone rubber compound sheds molten metal splashimmediately, so very little heat transfer occurs. Fireproof sleeve also may beused to insulate your race cars plumbing system.Excellent modulus of elasticity makes it an ideal choice for bundling hoses,tubes and cables in a variety of hostile environments.Inner Diameter(mm) Tolerance(mm) Wall thickness(mm) Meters/roll6-22 ±0.5 3.0±0.3 20 mts.25-40 ±0.8 3.2±0.3 20 mts.45-95 ±1.0 3.5±0.4 20 mts.100-152 ±1.2 4.0±0.5 20 mts.Breakdown Voltage: when Normal Condition alternating current 50HZ, canreach 30,000 Volts,so it has good dielectric strength.Colour: brick red.Guard against fraying and absorptionFire Sleeve is designed to protect hoses, wires and cables from the hazards of highheat and occasional flame. It protects continuously to 260ºC a. Made of Bulkfiberglass yarns in a flexible substrate, it is then coated with a high grade siliconerubber.Resistant to hydraulic fluids, lubricating oils, and fuels, Silco Sleeve insulates againstenergy loss in piping and hosing; protects employees from burns; and allows"bundling" of wires, hoses, and cables.This is the perfect cover to protect hydraulic hoses, pneumatic lines and wiringbundles.Glassfiber sleeve - Quick FactsSizes up 1/4"(6.3 mm) to 6" (152 mm) diameter.Continuous operating temp of outsidepart(namely is silicone coating) : 260°CContinuous operating temp of braidingpart(namely is inner glass fiber ) : 550°CMax short term exposure: 2000°F (1050°C)Molten splash resistance: OutstandingFlame resistance: Very goodAbrasion resistance: Very goodFlexibility: OutstandingWater and oil resistance: Outstanding.
