In demanding industrial environments, hoses, cables, and wiring are constantly exposed to heat, abrasion, and harsh operating conditions. A silicone coated heat sleeve is a simple yet powerful solution that protects these components and extends their service life. Manufactured with a flexible fiberglass base coated in premium silicone rubber, this heat sleeve offers excellent resistance to high temperatures, oils, chemicals, and mechanical wear.
At BSTFLEX, we specialize in producing high-performance silicone coated heat sleeves with diameters from 4 mm to 150 mm, ensuring reliable protection for hydraulic systems, automotive assemblies, and industrial equipment operating under extreme temperatures.
The silicone coated heat sleeve is designed to withstand continuous exposure to temperatures up to 260°C (500°F) and short-term radiant heat peaks up to 1000°C (1832°F). This outstanding thermal protection prevents hose damage, fluid degradation, and system failures, making it ideal for applications near engines, exhausts, or furnaces.
Industrial hoses and cables often experience friction or impact from surrounding components. The silicone coating provides a strong outer barrier that resists cuts, scuffs, and surface wear. Even in high-motion or high-pressure environments, the sleeve maintains its integrity, significantly extending equipment lifespan.
In many manufacturing and mechanical settings, exposure to oils, coolants, and hydraulic fluids is unavoidable. The silicone outer layer forms a tight, non-porous seal that prevents chemical penetration and moisture absorption. This protection keeps the internal fiberglass insulation dry and effective, ensuring consistent performance over time.
The silicone coated heat sleeve not only withstands heat but also resists flames and electrical leakage. Its non-conductive nature provides an additional safety layer for electrical wiring and control cables in high-temperature zones. This makes it a preferred choice for automotive, aerospace, and power generation industries.
Despite its robust structure, the sleeve remains highly flexible, allowing quick and simple installation over hoses or cables. It can be easily cut to any length and secured with clamps or ties. The smooth silicone surface ensures it slides into place without snagging or fraying, saving time during maintenance or assembly.
By shielding hoses and wiring from thermal and mechanical stress, the silicone coated heat sleeve helps prevent premature failures. This leads to fewer replacements, less downtime, and reduced maintenance costs — key advantages for industries where reliability and efficiency are critical.
