Product Description
The 99-4886 is a Teflon (PTFE) flat washer designed for aircraft fastener applications. This nonmetallic washer provides electrical isolation and low-friction bearing surfaces under AN/MS bolts and screws. PTFE's chemical resistance makes it ideal for fuel, hydraulic, and avionics assemblies where metal-to-metal contact causes galling or fretting.
Install under fastener heads or nuts to minimize torque scatter in control linkages and prevent surface damage. Follow aircraft maintenance manual torque specifications when using polymer washers, as PTFE requires lower clamping forces than metal washers.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
