Fire sleeve is a common term for a Silicone coated fiberglass sleeve, generally used in industrial or aerospace applications. Fiberglass acts as an insulator or barrier for constant temperatures up to 540ºC. Silicone is generally able to withstand temperatures up to about 260C degrees continuous. Silicone, however, has the added benefit of being able to withstand and repel much higher temperatures for short durations, including liquid molten metals. Fire sleeve is used as a protective sleeve on industrial hoses, hydraulic hoses, cables, wires, etc. Fire sleeve generally refers to two variations: An aerospace version is made with a braided fiberglass substrate and is commonly used in the aerospace industry. Its construction enables qualified hose assemblies to meet the SAE standards which have been established relative to the protection which this product provides. An industrial version, constructed of a knitted fiberglass substrate is also available. Because it is less expensive it is more commonly used in hot industrial applications where this type of protection is needed. The industrial version will not meet the SAE standards. Fiberglass sleeve—without the Silicone rubber coating—has a higher continuous temperature rating, up to 1000ºF or 540ºC and is available as a knitted or braided sleeve for protection of hoses and cables where molten splash protection or weld splatter protection is not required. Fire sleeve is used for industry, aerospace, automotive, mining.
