Abstract
A high pressure seal assembly configured for sealing contact with an opposing surface. The seal assembly comprises an annular seal body with a sealing surface on one side of the seal body. An end of the sealing surface includes a sealing face for sealing contact with the opposing surface. The sealing surface also includes at least one support point that contacts the opposing surface when the seal is placed in sealing contact. Strategically positioning the support point on the sealing surface selectively adjusts the sealing contact stress between the sealing face and the opposing surface.
