INSUL SLEEVE/WSHR (P/N k3300) - New Surplus

The k3300 is an insulating sleeve and washer set that electrically isolates fasteners from aircraft structure. This nonmetallic component prevents electrical shorts and galvanic corrosion where conductive fasteners mount to composite or aluminum airframes. Manufactured from aerospace-grade plastic or phenolic material per NAS1515 or NAS549 standards.

Install the sleeve through the mounting hole with the washer positioned under the fastener head to maintain electrical isolation during assembly. Essential for electrical equipment installations, avionics mounts, and antenna attachments where fastener-to-structure contact must be prevented.
