An improved tubular joint (10) includes an inner tubular member (14), an outer tubular member (12) having a central bore (13) therethrough, a counterbore (18) extending from the open end of the central bore and terminating in a shoulder (32) between the counterbore (18) and the central bore (13), and internal threads (36) on the outer end of the counterbore. A sleeve (16) is positioned within the counterbore and a retainer ring (20) is threaded into the counterbore threads and retains the sleeve within the counterbore. Ribs (22) are formed on the interior of the sleeve and a seal (24) is provided between the exterior of the sleeve and the interior of the counterbore so that pressure forming of the inner tubular member forms it into tight gripping and sealing engagement with the sleeve and the sleeve is sealed within the outer tubular member to form a completed improved tubular joint. |
