The main difference between braided hydraulic hose fire sleeve and knitted silicone fire sleeve lies in the materials and construction, which affect their performance and application.

1. Braided Hydraulic Hose Fire Sleeve:

   • Construction: This sleeve is typically made from a high-temperature resistant material like fiberglass or silica, with a braided outer layer of fiberglass or aramid fibers.
   • Performance: The braided design offers added strength and abrasion resistance, making it well-suited for high-pressure hydraulic hoses, where durability and wear-resistance are critical.
   • Protection: It provides excellent protection against heat, flames, and physical damage. It is commonly used in environments with high mechanical stress.
   • Flexibility: Braided sleeves are generally more flexible than their knitted counterparts, allowing for easier installation and use on more complex hose assemblies.

2. Knitted Silicone Fire Sleeve:

   • Construction: This sleeve is made from a silicone-coated fiberglass material, with a knitted weave structure.
   • Performance: The knitted design tends to be more lightweight and flexible than braided versions, but it may offer slightly less mechanical abrasion resistance. It excels at thermal insulation and heat protection, especially in environments where high temperatures and occasional flame exposure are a concern.
   • Protection: The silicone coating provides superior thermal resistance (up to around 500°F or more), offering great protection for hoses or wires that are exposed to extreme heat or fire.
   • Flexibility: Knitted fire sleeves are usually more pliable and stretchable, making them ideal for applications requiring easy installation or covering hoses with irregular shapes.

Summary of Differences:

• Strength: Braided fire sleeves offer more abrasion resistance and mechanical protection compared to knitted silicone sleeves.
• Flexibility: Knitted silicone sleeves are generally more flexible and easier to install.
• Temperature Resistance: Both types offer strong heat resistance, but braided sleeves often provide better mechanical protection, while knitted silicone excels at thermal insulation.

Application:

• Use a braided hydraulic hose fire sleeve for applications involving high pressure, mechanical stress, or where additional abrasion resistance is needed.
• Opt for a knitted silicone fire sleeve for thermal insulation in less mechanically demanding environments where flexibility and ease of installation are key.
