Aluminum Coated Fiberglass Self-Closing Wrap Sleeving
The E-FLEX® Aluminum Fiberglass Sleeve is a high-performance thermal barrier engineered from an aluminum foil laminate, fiberglass, and polyester composite. This advanced multi-layer construction delivers exceptional radiant heat reflection and thermal insulation, protecting sensitive wire harnesses and hoses from extreme engine bay temperatures.
Featuring a split self-wrapping design with an integrated high-temperature adhesive strip, the AFS series allows for rapid retrofitting onto pre-installed components without disassembly. It is the premier choice for automotive and industrial applications where oil resistance, fire safety (FMVSS 302), and long-term thermal integrity are paramount.
Feactures and benefis
Exceptional Radiant Heat Reflection: Efficiently reflects up to 90% of radiant heat, maintaining internal temperatures significantly lower than the environment (Ref. SAE J2302).
Rapid Retrofit Design: Split-wrap geometry with a 25% overlap ensures 360° protection and easy installation over complex assemblies.
Integrated Secure Seal: Features a professional-grade, high-temperature adhesive closure to prevent slippage in high-vibration automotive zones.
Industrial Chemical Resilience: Engineered to withstand exposure to gasoline, engine fluids, and corrosive chemicals without delamination (Ref. GMW15608).
