ABSTRACT:
A micromechanical seal between a first body and a second body, which is axially threadably securable to the first body, is formed by the combination of a first annular concave radial surface upon the first body, the first surface defining a radius of curvature in the range of about two to about eight ten-thousandths of an inch, a second annular concave radial surface upon the second body, the second surface fully complemental in inner and outer radial dimensions to the first surface, the second surface defining a radius of curvature in the range of about two to about eight ten-thousandths of an inch. Upon tightening of the respective axially threadedable surfaces of the first and second bodies, a micromechanical seal in a region of compression, formed by the opposing concave surfaces, is created.
