Claim Text:
1. A metal-to-metal sealing system connecting first and second tubular members comprising: a metal-to-metal sealing system connecting first and second tubular members comprising: a first seal configuration on the first tubular member including a first annular groove and a first annular tooth, the first annular groove defined by a radially inward facing undercut surface, an adjacent first annular shoulder face and an adjacent first radially outward facing surface, the first annular tooth defined by the radially inward facing undercut surface, a first annular tooth face and a second radially outward facing surface; a second seal configuration on the second tubular member including a second annular groove and a second annular tooth, the second annular groove defined by a radially outward facing undercut surface, an adjacent second annular shoulder face and an adjacent first radially inward facing surface, the second annular tooth defined by the radially outward facing undercut surface, a second annular tooth face and a second radially inward facing surface; wherein the second annular tooth is positioned within the first annular groove with the second annular tooth face engaging the first annular shoulder face to define a first shoulder; wherein the first annular tooth is positioned within the second annular groove with the first annular tooth face engaging the second annular shoulder face to define a second shoulder; wherein a location of primary sealing contact between the first radially outward facing surface of the first tubular member and the second radially inward facing surface of the second tubular member is spaced axially away from the first shoulder, such that there is a first axial distance between the first shoulder and the location of the primary sealing contact; wherein the location of primary sealing contact between the first radially inward facing surface of the second tubular member and the second radially outward facing surface of the first tubular member is axially spaced from the second shoulder, such that there is a second axial distance between the second shoulder and the location of the primary sealing contact.
