Abstract: A sealing system adapted for placement into an exterior groove of a structure. The sealing system includes a seal ring having a generally ‘L’-shaped cross-section. The sealing system further includes a canted-coil spring. The seal ring includes an inner surface, an outer surface and two side surfaces.
