A flanged end (98) of a section of tubing (90) is received within a tubular portion (112) of a first member (104) which includes a threaded end portion (110). An elastomeric O-ring (116) snugly surrounds the section of tubing (90) and contacts the flange (98). An elongated sleeve (120) surrounds the tubing section (90) and at its inner end (124) contacts the O-ring (116). A radial surface (144) on a second member (128) contacts a radial shoulder surface (126) on the sleeve (120). The second member (128) makes a threaded connection (110) with the first member (104). When the threads (110) are tightened, the radial surface (144) on the second member (128) applies an axial force on the shoulder (126), moving the sleeve (120) into compressing contact against the O-ring (116), but without transferring torque to the flange (98) at the end of the tubing section (90 ).
