ABSTRACT:
A ring seal primarily for sealing static mating faces comprises an annular jacket (1), which may be made of low friction plastics material, having a channel of part-elliptical radial profile. Within the channel there is accommodated an energizing spring (2) in the form of a ring of channel-shaped radial profile, there being a gap between a part (M) of the spring ring (2) and the channel to allow movement of the spring ring relative to the jacket when the ring seal is brought into use. The spring ring (2) is made from a transversely folded strip of metal with segmented side edges which is formed into a circle and then has its ends secured together.
