Abstract

A sealing element (10) for use in establishing a seal in an annulus (50) between a mandrel (52) and a bore wall (54) comprises an annular body (12) which defines a through bore (14) to permit mounting of the sealing element (10) on a mandrel (52), and further defines an inner surface (16), an outer surface (18) and opposing axial ends (20, 22). A pair of inner circumferential grooves (24, 26) are formed in the inner surface (16) of the annular body (12), wherein each groove (24, 26) is defined by first and second opposing ramp surfaces (224a, 24b, 26a, 26b) extending from the inner surface (16) of the annular body (12), wherein the first ramp surface (24a, 26a) defines a shallower ramp angle than the second ramp surface (24b, 26b). The ends (20, 22) of the body (12) are configured to receive an axial setting force to axially compress the annular body (12) and cause radial expansion thereof to, in use, establish a seal between the inner surface (16) and the mandrel (52), and the outer surface (18) and a bore wall (54).
