ABSTRACT:
A ring seal of the kind comprising an annular jacket (1) of relatively yieldable material with a channel containing an energizing spring to impart resilience thereto, is characterized in that the channel is of substantially part-elliptical profile and contains a partly spaced spring ring (2) of channel shaped radial profile. The spring ring comprises a pair of metal rings (2a, 2b) which have axial slits and are secured together around their outer periphery prior to insertion in the jacket channel. Additionally the spring ring may have a plane circular ring welded thereto in a central diametric plane and to this latter ring there may be secured a dual component cylindrical protection ring having its axis coincident with the axis of the ring seal.
