A self-energizing one piece seal (10) has an annular seal body (11) and a multiplicity of circumferentially spaced delta shaped resilient tabs (12) extending inwardly from the annular body (11). The seal (10) is adapted to be placed in an annular groove (11) of a cylindrical member (19) so that a circumferential seal face (13) is initially biased into sealing engagement with a bore (22) of a valve body (23) and a radial seal face (14/16) is initially biased into sealing engagement with a radial face (31/32) of the groove (29) by the resilient tabs (12).
