WASHER (P/N nas1598-3y) - New Surplus

The NAS1598-3Y is a sealing washer combining a steel retainer with NBR elastomer packing per NAS 1598 specifications. This component creates a fluid-tight seal under fastener heads and fitting connections, preventing leakage around screws in hydraulic, fuel, and pneumatic systems. The elastomer packing compresses when fastened, while the steel retainer maintains structural integrity under pressure cycling.

Installation requires sizing the washer to match the joint diameter and torquing per aircraft maintenance manual specifications. Common in general and commercial aviation fluid system assemblies.
