INSULATOR (P/N 690a) - New Surplus

The 690a is a non-conductive aircraft insulator for electrical isolation at feed-through bulkheads and structural interfaces. This component prevents unwanted bonding between conductors and airframe structure while maintaining dielectric strength and creepage distance per aircraft wiring standards. Used in avionics systems, electrical harnesses, and control circuits where isolation is required.

Install and torque hardware per FAA AC 43.13-1B guidance and applicable aircraft maintenance manual specifications.

What is the INSULATOR (P/N 690a)?

The 690a is a non-conductive aircraft insulator for electrical isolation at feed-through bulkheads and structural interfaces. This component prevents unwanted bonding between conductors and airframe structure while maintaining dielectric strength and creepage distance per aircraft wiring standards.

Is the 690a compatible with my aircraft's avionics suite?

Avionics compatibility depends on your aircraft model and existing installation. The INSULATOR is available in: New Surplus. We recommend checking your aircraft's wiring diagrams and STC documentation, or contact our avionics team for compatibility assistance.

Does the 690a come with an 8130-3 airworthiness tag?

Availability of an FAA 8130-3 tag depends on the part condition. Overhauled and repaired units typically include 8130-3 documentation. As-removed units may include a removal tag with trace history. Contact us for specific documentation on the condition you need.

Do you offer bench testing for the 690a?

We can arrange bench testing through our network of FAA-certified repair stations. Call (904) 998-9101 for testing availability and turnaround times, or submit an RFQ with your specific requirements.
