Silicone Coated Fiberglass Heat Shielded Fire Sleeve
E-FLEX® Fiberglass Fire Sleeve is engineered for extreme thermal shielding, the E-FLEX® Fire Sleeve combines premium alkali-free fiberglass with an advanced iron oxide red silicone coating. Through a specialized high-temperature curing process, this heavy-duty sleeve delivers a multi-functional barrier against flames, molten metal splashes (up to 3000°F/1650°C), and high-voltage arcing.
Trusted for its exceptional chemical, acid, and alkali resistance, E-FLEX® Fire Sleeve ensures the operational integrity of hydraulic hoses, critical wiring, and metal pipelines in the harshest industrial environments. With UL-certified VW-1 flammability and a dielectric strength up to 25kV, it is the premier choice for aerospace, smelting, and heavy machinery where system safety is non-negotiable.
Feactures and benefits
Extreme Thermal Resilience: Sustains continuous operation at 260°C, withstanding short-term peak exposure to molten splashes up to 1650°C (3000°F).
High-Voltage Dielectric Barrier: Exceptional nominal voltage protection ranging from 7kV to 25kV, preventing electrical failure in dense circuitry.
Chemical & Environmental Inertia: Superior resistance to industrial acids, alkalis, and oils, ensuring long-term structural stability without degradation.
Certified Industrial Safety: Fully compliant with UL/VW-1, RoHS, and REACH standards; engineered for mission-critical risk mitigation.
Tailored Engineering Support: Backed by MJ-IST proprietary technical data, supporting custom colors and specialized sizing for global OEM projects.
