The NAS1523-4R is a bonded sealing washer designed for face sealing beneath bolt and screw heads in aerospace assemblies. This seal combines a metal retainer with a molded elastomer element to create a leak-free interface at fastener through-holes. Commonly used in aircraft fuel system covers and fittings, the washer installs flat against the surface before the fastener is tightened.
Installation requires torquing to the specification outlined in the applicable aircraft maintenance manual to ensure proper compression and sealing performance.
