ABSTRACT A ring seal of the kind comprising an annular jacket of relatively yieldable material with a channel containing an energising spring to impart resilience thereto, is characterised in that the channel is of substantially part-elliptical profile and contains a partly spaced spring ring of channel shaped radial profile. The spring ring comprises a pair of metal rings 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.
