PRODUCT DESCRIPTION

26916-004

  • Electrical insulation: Prevents accidental electrical contact and short circuits between conductors and structure.

  • Thermal protection: Reduces heat transfer to nearby components from hot ducts or equipment.

  • Durable construction: Made from aviation-grade insulating materials selected for wear and solvent resistance.

  • Low profile design: Slim form keeps clearance requirements minimal while still providing protection.


  • Covers bundles in avionics bays to prevent chafe and accidental shorts during maintenance.

  • Guards nearby sensors and wiring from heat near bleed-air ducts or exhaust fairings.

  • Fits over panel connectors during engine runs or ground testing to avoid fluid ingress.

  • Separates battery terminals from nearby structures in service and storage.


  • What is this insulator cover made of?

It is made from certified aviation insulating materials chosen for electrical isolation, thermal resistance and fluid compatibility.

  • How is the cover attached?

Typical attachment is by factory-provided clips, Velcro straps, or simple screws. The installation method depends on the specific aircraft location.

  • Does it affect airflow or cooling?

The design minimizes impact on ventilation if fitted near cooling paths. Follow OEM guidelines to ensure the required airflow is maintained.
