Abstract
A method of sealing at least a first seal surface to a second seal surface comprises the steps of placing a flexible ring member between the first and second seal surfaces and juxtaposing the first and second seal surfaces. The flexible ring member is compressed between the first and second seal surfaces. Thereafter, the flexible ring member is expanded into at least one of a first recessed area in the first seal surface and a second recessed area in the second seal surface, with at least one of the first and second recessed areas having a plurality of spaced apart pressure points that contact the ring member. This method of sealing assures that when the O-ring (flexible ring) permanently sets over time, it takes the shape that makes the seal effective for a long time under high temperature, high pressure.
