ABSTRACT:
A stacked seal is built up from an integral unit that consists of annular rings molded together in a coplanar, non overlapping series by plurality of alternately facing live hinges. The hinges are wide enough to establish a straight folding axis between adjacent pairs of rings so that they can be serially folded, one concentrically on the other, and the proper length to assure that the rings fold flat. Integral latch means self retain the rings in a stack so as to be easily installed.
