摘要： A method of forming a fluid-tight seal between two surfaces including the steps of forming at the surfaces to be sealed an annular recess for the sealing elements, the recess having a cylindrical outer surface and being wedge-shaped in radial section, tapering inwards, and with a radius curve between the outer and the wedge surfaces, and fitting into the recess sealing elements comprising an O-ring surrounded by a collar of a plastics material which is flexible but does not flow under the conditions in which the seal is required to operate, the relative dimensions being such that the ring and collar are deformed on tightening the seal, and then tightening the surfaces together to compress the O-ring and to deform the collar against the surfaces of the sealing recess.
