A fire sleeve is a protective covering designed to provide flame resistance to hydraulic hoses. It is typically made of a woven fiberglass or similar material coated with a high-temperature resistant silicone or other fire-resistant compounds. The fire sleeve is slipped over the hydraulic hose to provide an additional layer of protection against heat, flames, and molten metal splash.

Fire sleeves are commonly used in industries where hydraulic systems are exposed to high temperatures or potential fire hazards, such as in mining, steel mills, foundries, and firefighting equipment. They help to prevent hydraulic hoses from burning or melting in the event of a fire, providing vital protection to the hydraulic system and reducing the risk of injury to personnel.

Fire sleeves can withstand high temperatures and offer resistance to flame, heat, and abrasion. They also provide insulation for the hydraulic hoses, helping to maintain the efficiency and performance of the hydraulic system.
