The invention is a sealing system that employs a unique array of offset components, including multiple seal rings(42, 44), and is used in a flexible connection (1) to provide an improved seal with enhanced functionality. In the preferred embodiment, a groove (24) contains two canted-coil springs (38) that are located in a side-by-side relation beneath a pair of expander rings (40) that are also in a side-by-side relation. Located atop the expander rings are three seal rings (42, 44) that are similarly arrayed in a side-by-side relation. To prevent a leak path through the expander rings (40), a center one (44) of the seal rings overlies the area (50) between the two expander rings (40). |
