Abstract

A clamped flange pipe or tube fitting assembly includes a resilient seal ring compressed in a chamber formed by cooperating recesses in opposed flanges. The chamber and seal ring are dimensionally related in a manner to produce circumferentially continuous, radially spaced primary and secondary seal areas and to assure a continuous interior surface between the connected pipes or tubes with no recesses to entrap process fluids.
