Flexible silicone rubber coated fiberglass / fibreglass / glassfibre sleeve is generically called Firesleeve.  The base fiberglass sleeve material is available in a knitted form or a braided form, of E-Type yarns, and is then coated with high-temperature silicone rubber.  The base material will not burn and the silicone rubber coating is self-extinguishing (beware as some firesleeve is not self-extinguishing due to impurities in the silicone rubber!).

Firesleeve is also spelled "Fire Sleeve" or "Fire-Sleeve" and is available in sizes from 0.250" / 6mm Inside Diameter (I.D.) through 5.0" / 127mm I.D.  Special small diameter firesleeve, usually used for bare wire protection, is available in sizes from 0.022" ID through 0.234" ID from the Firesleeve and Tape website.  Firesleeve made from a knitted sleeve is usually called Industrial Firesleeve, while firesleeve made from a braided sleeve is called Aviation or Marine Firesleeve. Aviation and Marine firesleeve is made to SAE AS1072 specifications so that hose assemblies can pass the fire testing of AS1055.

Firesleeve is manufactured in long lengths of several hundred feet, and is then packaged into 100 foot lengths or random long lengths totaling 100 feet.  The most common use of firesleeve is to protect industrial hydraulic hoses, wire, cables, tubing and pipe in plants where molten metal is processed, such as a steel or aluminum plant, or in areas of robotic welding where there is weld splatter.  In aviation and marine use, firesleeve is used to protect fuel lines, hydraulic and oil lines from fire; to delay the failure of these critical hoses in case of an engine-compartment or engine-room fire.

Firesleeve also provides a high degree of insulation value, protecting hot or cold or cryogenic lines, pipes and tubing from heat or cold loss, providing energy savings.  As the outer silicone rubber coating is non air-permeable, it prevents pipe sweating or freezing.  Multiple layers of firesleeve can provide very high R-values.
