A Rotary Feedthrough A rotary feedthrough (22) between first (12) and second (11) relatively rotatable components includes a fluid seal (31, 32) having a body (31a, 32a) comprising an elastomeric material mounted to a supporting surface (50) of one of the components (11). The body has a pair of spaced sealing members (31c, 32c) for engagement with a sealing surface (30) on the other component to define a high-pressure area (40, 41) between them. Said one of the components includes a pressurised fluid passage (25, 28) fluidly connected with the high– pressure area which comprises an annular recess (25a, 28a) which opens at the supporting surface and extends radially outwardly of the supporting surface and a bore (25b, 28b) which opens into the recess at a position offset radially outwardly from the supporting surface. The elastomeric body (31a, 32a) of the seal engages with the supporting surface (50) either side of the recess. The rotary feedthrough (22) enables the seal to be pressed into position without passing over splinters or bores formed when the bore is produced.
