Abstract
A tubular coupling assembly is disclosed which includes a pair of identical coupling members secured together by a splined stud. A sleeve member is inserted between the identical members to provide a leak free fluid pathway between the coupling members.
Claims13
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;
- and
- a 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.

A tubular coupling assembly, comprising:
- a pair of coupling members having matingly engagable surfaces, each said coupling member having an aperture formed therethrough with an interior surface and terminating at said engagable surface;
- a pair of tubular portions each terminating in a hollow expanded portion connected to said tubular portion by a hollow transition portion, each said expanded portion secured in an associated one of said coupling member apertures 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 having a radially extending center seal with a radial diameter greater than a radial diameter of each of said sealing members;
- and
- a stud, each said coupling member having a radially extending stud receiving block member with an aperture formed therethrough, said stud being fixed in 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.

The tubular coupling assembly, comprising:
- a pair of coupling members having matingly engagable surfaces, each said coupling member having an aperture formed therethrough with an interior surface, each said engagable surface having an annular recess formed therein encircling said termination of said aperture;
- a pair of tubular portions each terminating in a hollow expanded portion connected to said tubular portion by a hollow transition portion, each said expanded portion secured in an associated one of said coupling member apertures having a flange formed at one end thereof received in said recess 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 having a radially extending center seal with a radial diameter greater than a radial diameter of each of said sealing members;
- and
- a stud, each said coupling member having a radially extending stud receiving block member with an aperture formed therethrough, said stud being fixed in 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.
