A face seal fitting between two conduits which define an axial flow path is disclosed. The conduits have annular noses projecting from the ends which engage the opposite surfaces of a metal gasket to make engagement. The gasket has a first outer region with surfaces perpendicular to the axial flow path, a second beveled sealing region for engagement with the noses and a third inner region which defines a restrictive orifice.
