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. The seal ring's inner surface features a groove that increases the ring's flexibility. The seal ring's outer surface protrudes outwardly until it is pushed inwardly through contact with an inner surface of an external structure. As the outer surface moves inwardly, it causes a compression of the spring while a part of the seal ring flexes and bends about the seal ring's groove. At the same time, the outer surface becomes reoriented in a manner that cause its shape to change to a flatter configuration that is more complementary to the inner surface of the internal structure.
