A silicone coated fire sleeve provides protection for hydraulic hoses and cables through several mechanisms:

1. Thermal Insulation: The fire sleeve is made of a high-temperature-resistant silicone coating over a fiberglass sleeve. This construction provides excellent thermal insulation, preventing heat from reaching the hydraulic hoses and cables.

2. Fire Resistance: The silicone coating is inherently fire-resistant, which helps to protect the hoses and cables from flames and intense heat. It can withstand high temperatures for extended periods, thereby preventing damage during exposure to fire.

3. Abrasion Resistance: The silicone-coated sleeve offers superior resistance to abrasion, protecting the hoses and cables from physical damage caused by rubbing against other surfaces or objects.

4. Moisture and Chemical Resistance: The silicone coating provides a barrier against moisture, oils, fuels, and various chemicals, ensuring that the hydraulic hoses and cables remain unaffected by these substances.

5. Containment of Heat: In case of a fire, the sleeve helps to contain the heat within itself, reducing the risk of the heat spreading to other components and causing further damage.

6. Flexibility and Durability: The combination of silicone and fiberglass results in a flexible yet durable sleeve that can withstand harsh operating conditions, including vibration, bending, and exposure to the elements.

Overall, a silicone coated fire sleeve extends the lifespan of hydraulic hoses and cables by providing comprehensive protection against multiple environmental and operational hazards.
