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.

1. A method of sealing at least a first seal surface to a second seal surface, comprising the steps ofproviding a recessed area in said first seal surface, said recessed area comprising a first divided seal surface divided by at least one recessed section, wherein each of said recessed sections has a plurality of spaced apart pressure points, and wherein said recessed area is larger than each of said recessed sections; providing said second seal surface comprising a second divided seal surface divided by at least one of said recessed sections, wherein each of said recessed sections has at least one plurality of said spaced apart pressure points; placing a flexible ring member between said first and second seal surfaces; juxtaposing said first and second seal surfaces in compression; compressing said flexible ring member in said larger recessed area between said first and second seal surfaces; and expanding said flexible ring member into at least one of said recessed sections in each of said first and second divided seal surfaces so that at least one of said plurality of spaced apart pressure points in each of said seal surfaces contacts said flexible ring member.
