Aluminum foil coated fiberglass sleeve special designed by laminating an aluminized metallic heat shield to a layer of strong and tight braided fiberglass yarn. A special manufacturing process permits the sleeve to boast a virtually seamless and non fraying construction. This aluminized fiberglass sleeve reflects more than 95% of the radiant energy that hits its surface, keeping the underlying cables, hoses and wires cool.

E-FLEX® Self-Adhesive Aluminum Foil Fiberglass Self-Wrapping Sleeve combines high-performance radiant heat reflection (SAE J2302) with a self-closing, high-temperature adhesive seal to provide a rapid, professional thermal barrier for critical harnesses in extreme engine and industrial environments.
