Product Description
Fire Protective Cable Protection Silicone Coated Fiberglass Wire Sleeve is a high temperature insulating sleeve developed to protect electrical cables, wire harnesses, hydraulic lines, and industrial hoses from radiant heat, direct flame, abrasion, and molten splash. Built with a braided fiberglass core and a durable silicone rubber coating, it provides dependable thermal shielding and fire resistance in demanding industrial and automotive environments. Inner diameters from 4 mm to 150 mm are available. Standard colors are red and black, and custom colors can be produced on request.
Product Overview
Fire Protective Cable Protection Silicone Coated Fiberglass Wire Sleeve is engineered for applications where wires, cables, hoses, and tubing must operate safely in the presence of elevated temperatures, flame contact, and aggressive mechanical conditions. The sleeve is manufactured from a high strength fiberglass braid coated with specially formulated silicone rubber, creating a flexible yet durable protective barrier.
This construction gives the product excellent resistance to heat transfer, flame exposure, abrasion, oil contamination, and environmental wear. It is widely used where thermal protection and fire safety are critical, especially in engine compartments, steel processing lines, railway systems, welding equipment, heavy machinery, and electrical installations.
Compared with standard insulation sleeves, silicone coated fiberglass wire sleeve offers improved resistance to open flame, better handling of intermittent extreme temperatures, and stronger overall durability in industrial service. It also helps extend the working life of cables and hoses by minimizing thermal aging, cracking, and outer surface damage.
The product is available in a broad inner diameter range from 4 mm to 150 mm, making it suitable for both fine wire bundles and large industrial hose assemblies. Standard supply colors are black and red, while custom colors can be arranged for identification, branding, or project requirements.
Supported by multiple quality certifications and laboratory test standards, this sleeve is a practical solution for OEM buyers, equipment manufacturers, distributors, and industrial maintenance professionals looking for reliable fire resistant cable protection.
