Product Description
Universal Wholesale Silicone Rubber Fiberglass Silicon Fire Sleeve is a high temperature protective sleeve manufactured for thermal insulation, flame shielding, and abrasion protection of hoses, cables, pipes, and wire bundles. Built with a braided fiberglass core and coated with premium silicone rubber, this fire sleeve delivers dependable performance in continuous heat, direct flame exposure, and harsh industrial environments.
Designed for OEM supply, wholesale distribution, and industrial projects, this silicone fiberglass fire sleeve is widely used in hydraulic systems, steel plants, railway equipment, automotive engines, marine machinery, and electrical cable protection. It helps reduce radiant heat transfer, protects valuable components from molten splash and mechanical wear, and extends the service life of hoses and cables working under extreme conditions.
Available in inner diameters from 4 mm to 150 mm, this heat resistant sleeve can fit both small wire harnesses and large industrial hoses. Standard colors are red and black, while custom colors can be produced for identification, branding, or project requirements. With broad compliance support including ISO 9001:2015, IATF 16949, MSHA, UL 1441, RoHS, and REACH, this product is an ideal choice for buyers seeking safe, durable, and certified high temperature insulation sleeves.
Product Overview
Universal Wholesale Silicone Rubber Fiberglass Silicon Fire Sleeve is developed to protect critical lines and components exposed to heat, flame, sparks, oil splash, and abrasion. The inner braided fiberglass structure provides thermal stability and strength, while the outer silicone rubber coating adds fire resistance, flexibility, weather resistance, and surface durability.
This combination allows the sleeve to operate in demanding industrial and mechanical applications where standard sleeving materials fail. It is especially suitable for hydraulic hose assemblies, industrial cable routing, pipe insulation, engine bay heat shielding, and railway or heavy equipment thermal protection systems.
For importers, distributors, and equipment manufacturers, this fire sleeve provides a practical and scalable solution. It supports custom sizes, custom colors, cut lengths, and bulk production, making it suitable for both replacement supply and OEM integration.
