[ What is claimed is:] [1.] A tubular coupling assembly, comprising:a pair of coupling members having matingly engagable surfaces, each said coupling member having a tubular portion connected to a hollow expanded portion by a hollow transition portion, said expanded portion terminating at said engagable surface and being encircled by an annular recess formed in said engagable surface such that when said engagable surfaces are in contact with each other, and a volume being defined by said expanded portions having a larger diameter than a diameter of said tubular portions;a generally cylindrical, elongate sleeve member disposed within said volume, said sleeve member having an outer surface with a plurality of circumferential sealing members radially extending therefrom into sealing contact with interior surfaces of said expanded portions, said sleeve member including a circumferential center seal radially extending into sealing contact with said annular recesses, said center seal having a radial diameter greater than a radial diameter of each of said sealing members; anda stud, each said coupling member having a stud receiving block member extending radially from said expanded portion with an aperture formed therethrough, said stud being fixed by a press fit into one of said apertures in said stud receiving blocks and extending through another of said apertures in said stud receiving blocks to secure said coupling members together with said engagable surfaces in contact.
