Product Description
Fire Protective Silicone Rubber Coated Fiberglass Wire Insulation Sleeve is a high temperature insulating sleeve developed for protecting electrical wires, cable harnesses, hoses, and pipelines against radiant heat, direct flame, abrasion, and harsh industrial exposure. Constructed from braided fiberglass yarn and coated with premium silicone rubber, it delivers dependable thermal shielding, fire resistance, and long service life in demanding operating conditions. Available in inner diameters from 4 mm to 150 mm, with standard colors in red and black, and custom colors available.
Product Overview
Fire Protective Silicone Rubber Coated Fiberglass Wire Insulation Sleeve is engineered for critical heat and fire protection applications where cables, wires, hoses, and fluid lines operate near high temperature sources. The sleeve consists of a dense fiberglass braided inner core that provides thermal insulation and structural stability, combined with an outer silicone rubber coating that improves resistance to flame, oil splash, moisture, abrasion, and environmental wear.
This insulation sleeve is widely selected by OEM manufacturers, industrial distributors, and maintenance teams because it helps shield vulnerable components from heat damage, reduces energy loss, improves workplace safety, and extends the operating life of expensive systems. It is especially effective in environments exposed to continuous elevated temperatures, intermittent flame contact, and aggressive mechanical conditions.
The product is suitable for wire bundles, cable assemblies, hydraulic lines, fuel hoses, pneumatic systems, and pipe sections that require reliable fire protection and thermal insulation. With broad size coverage from 4 mm to 150 mm inner diameter, it can meet both compact electrical insulation requirements and large industrial hose protection needs.
Standard production colors are black and red. Other colors can be customized according to project identification, branding, or application-specific requirements.
Key Product Benefits
High temperature insulation for wires, cables, hoses, and pipes
Excellent fire protection against flame and extreme heat exposure
Silicone rubber outer coating for improved durability and environmental resistance
Fiberglass inner braid for thermal stability and mechanical reinforcement
Strong abrasion resistance for demanding industrial use
Effective shielding against molten splash, oil contamination, and harsh conditions
Wide size range from 4 mm to 150 mm inner diameter
Standard red and black colors with custom color options
Suitable for industrial, automotive, railway, marine, and heavy equipment applications
Main Product Features
This fire protective sleeve is designed to combine thermal insulation and mechanical protection in one flexible solution. Its braided fiberglass base creates a dependable heat barrier, while the silicone rubber surface improves handling performance and protects against external damage.
Compared with ordinary insulation sleeves, this product offers stronger flame resistance, better wear performance, and improved reliability in continuous service. It is commonly used in locations where direct heat, radiant heat, sparks, hot debris, or occasional flame contact may damage cables and hoses.
The sleeve remains flexible for easy installation and can be cut to required lengths for custom assembly, maintenance replacement, or large production runs.
