Resilient sealing rings are disclosed including an annular ring of resilient material having a cross-sectional configuration so that when not compressed the cross section of the sealing ring extends substantially longitudinally and when compressed between two parallel sealing surfaces the sealing ring bends so that the longitudinal ends approach each other. This provides acceptable compression force between the parallel sealing surfaces over an extended range of deformation particularly as compared to conventional O-rings. The use of such sealing rings in filtration and/or diffusion devices is also described, particularly in diffusion devices including a bundle of hollow fibers arranged longitudinally within a housing in which the fiber ends are embedded in end walls and in which a lid including an inlet or outlet for fluid which is intended to flow through the hollow fibers covers the end wall and in which these resilient sealing rings are positioned between the outside of the end walls and the inside of the lid.
