This procurement specification covers aircraft quality metallic gaskets having a “C” shape cross-section to form a seal ring, made from a corrosion and heat resistant age hardenable nickel base alloy of the type identified under the Unified Numbing System as N07750. Primarily for aerospace propulsion system applications for sealing fluids where operating temperatures excludes the use of elastomeric O-ring seals, and where the applications are relatively free from axial cyclic deflection, such as a bolted face type seal joint.
