Aluminum Foil Corrugated Heat Shield Wire Loom Tube

MJ FLEX WL-AF-N is an aluminum foil corrugated fiberglass sleeve engineered for reliable thermal shielding of cables, hoses and fluid lines. The integrated corrugated fiberglass substrate provides structural rigidity, while the outer aluminum foil layer reflects radiant heat away from internal components.

Its round tubular geometry maintains clearance around bundled wires, preventing hot-spot contact and cable tangling. The flexible corrugated ribs permit routing around corners and complex contours without collapsing.

    Typical Applications

    • Automotive Heat-Exposed Cable Routing

    Helps protect cables near engine-compartment heat sources and hot components from radiant heat exposure.

    • Industrial Equipment Wiring

    Adds thermal and external mechanical protection for wiring near heat-generating machinery components.

    • Flexible Ventilation Ducting

    May be used in compatible air-guidance routes subject to airflow, temperature and installation requirements.

    • Thermal Equipment Connections

    Supports flexible routing around equipment structures and obstructions.

    • Industrial Pipeline Protection

    External protective covering for compatible industrial lines exposed to heat and routine environmental contact.

     

    How to Select

    Measure the maximum outside diameter of the cable, hose or pipeline, including any section that must pass through the wire loom during installation. Select an inside diameter with enough assembly clearance without excessive looseness.

    Check operating temperature, distance from heat sources, routing length, bend radius and exposure to oil or moisture. For ventilation or flow-guidance applications, evaluate airflow, pressure conditions and connection methods. Avoid excessive compression, sharp bends and damage to the laminated structure. Validate critical assemblies under actual operating conditions.
