ABSTRACT A sealing assembly for sealing between two relatively rotatable cylindrical surfaces. The assembly comprises two seal parts (46, 48) disposed in a groove (40) in one of the surfaces so that one of said parts is disposed radially outwardly of the other. One (46) of the parts is movable axially relative to the other (48) to effect setting of the sealing assembly and the groove (40) and pasts (46, 48) are so dimensioned that they become compressed between the surfaces during setting of the assembly. Adjacent surfaces of the seal parts (46, 48) may have inter-engaging profiles (55) which permit relative movement for setting the assembly, but resist movement in the opposite direction.
