There is disclosed a seal assembly for sealing between the body of a valve and the closure member thereof, as well as a method for mounting the assembly within an annular groove with the body which surrounds the flowway through one side of the valve. The seal assembly comprises inner and outer seal rings of relatively hard and soft material which are locked within the groove by a resin which has hardened in the groove as the rings are held in predetermined endwise positions therein.
