A silicone fire sleeve is a high-temperature protective sleeve designed to shield hydraulic hoses, cables, and industrial lines from extreme heat, direct flame, and molten metal splash. It is commonly used in heavy-duty industrial environments where thermal exposure may cause hose failure or equipment damage.
Structurally, silicone fire sleeve consists of a braided fiberglass inner layer coated with a thick layer of high-grade silicone rubber. The fiberglass core provides excellent thermal insulation and structural stability, while the silicone outer coating delivers flame resistance, abrasion protection, and resistance to oil, moisture, and weathering.
The primary functions of silicone fire sleeve include reducing heat transfer to hydraulic systems, protecting hoses from flame and radiant heat, and preventing damage caused by molten metal splash. By maintaining safer operating temperatures, it helps extend hose service life and reduce unexpected downtime.
Silicone fire sleeves are widely used in steel mills, foundries, welding operations, mining equipment, construction machinery, and other heavy industrial applications where high-temperature protection is critical.
Silicone fire sleeve is designed to withstand continuous operating temperatures up to approximately 260°C (500°F). It can resist short-term exposure to molten metal splash or direct flame at temperatures up to around 1,000–1,200°C for brief periods.
The inner fiberglass layer provides thermal insulation, while the silicone rubber coating offers flame resistance and surface protection. Actual performance may vary depending on wall thickness, exposure duration, and installation conditions.
Yes, silicone fire sleeve is widely used to protect hydraulic hoses from direct flame, radiant heat, and molten metal splash. It helps prevent hose cover damage, reduces heat transfer to the fluid inside, and minimizes the risk of sudden hose failure in high-temperature environments such as steel mills, welding areas, and heavy machinery operations.
Proper sizing and secure installation are essential to ensure effective thermal protection.
Silicone-coated fire sleeve offers good resistance to hydraulic oil, lubricants, and common industrial fluids. The outer silicone rubber layer helps protect against oil splash, abrasion, weathering, and ozone exposure.
While it is not designed for continuous chemical immersion, it performs reliably in most industrial hydraulic and mechanical applications where incidental oil contact occurs. Always confirm compatibility for special chemical environments.
To select the correct diameter, measure the outer diameter of the hose or cable that requires protection. The inner diameter of the fire sleeve should be slightly larger to allow easy installation without excessive compression.
In high-vibration applications, proper fit is important to avoid slipping or bunching. For complex assemblies or multi-line bundles, custom sizing may be recommended to ensure full coverage and performance.
Yes, we provide customized silicone fire sleeve solutions based on specific project requirements. Custom options include different inner diameters, wall thickness, coating thickness, colors, pre-cut lengths, and bulk packaging.
OEM production and private labeling are also available for distributors and equipment manufacturers. Our team can assist with selecting suitable specifications according to temperature exposure, application environment, and industry standards.
