Abstract
A compound sealing ring for fluid couplings comprises an annular resilient seal member having front and rear ends between which extends a circumferential annular groove, and an annular rigid reinforcement member inserted over the front end of the sealing member in snug engagement in the groove. The reinforcement member is axially confined by the sidewalls of the groove and has sufficient rigidity to prevent radial outward deformation of the sealing member during use.
