Method of sealing one or more threaded connections between ends of a pair of tubular members configured to be rotatably threadably engageable. One of the members as an externally-threaded portion, with the other one having an internally- threaded portion. One of the threaded portions has a radial groove formed therein which is configured to receive a seal ring for sealing the connection. The groove of the one portion defines a void with the other portion, with the seal ring being compressed into the void by the engagement of the threaded ends of the members. The method involves determining a deformed axial cross-sectional geometries of the ends, mathematically revolving the deformed axial cross-sectional geometries to generate a corresponding solid of revolution, calculating the volume of the void by subtracting the open of the solid volumes from the other, and sizing the seal ring to overfill the void by a specified amount.
