Extrasil | Glass Fibre & Red Silicon

Insulating Sleeve for “Extreme Protection” at High Temperature

Glass Fibre Knitted Sleeve + Red Silicon, Type EXTRASIL 2236/SRX, TESPE is produced by Tespe in a special metodh, in order to obtain a very high wall thickness of Silicon (aprox. 1,5 mm), that makes it resistant to very high temperatures (260°C continuous working), to the hydraulic fluids, most acids and chemicals, lubricating oils and fuels and, for a short time, to sparks, weld spatter and molten metal.

Extrasil 2236/SRX

Diameter: from 10 mm to 125 mm
Rolls: 10 m

Other Products
