Abstract:

A face seal member includes a cylindrical annular body defining a cylindrical axis, a radial direction, a first axial extremity, a second axial extremity, an outside radial extremity and an inside radial extremity, a face sealing surface including a clearance surface, a contact region disposed radially adjacent the clearance surface that defines a contact plane, and a tapered surface extending radially from the contact region that defines a taper angle with the contact plane that increases as the tapered surface progresses further radially from the contact region toward the inside radial extremity.
