    • The invention relates generally to a metal-encased polymeric-lined tubing assembly (10) which is in leak-proof fluid communication with a connector (20). The assembly (10) comprises first and second essentially straight tubes (12,14), each of which has at least one tube end (16), which provides access to an internal conduit (42) in each tube (12,14). Each tube (12,14) is comprised of two components: a metal exterior (34) having an internal diameter (18); and a polymer tube (36) centrally disposed and at least partially inserted therein having an internal diameter (38). An insert (20) is used to connect the tube ends (16) of tubes (12,14). In one configuration, insert (20) has a central bulbous portion (22), with identical first and second nipple portions (24a, 24b) extending away from the bulbous portion. Other inserts (20), not shown, would have one nipple portion (24) with a larger diameter than the other or have the two nipple portions (24) aligned at an angle to each other. The exterior surface of the nipple portions (24a, 24b) will generally be provided with at least one circumferential rib (26) of slightly larger diameter and the distal end (28) of each nipple portion will generally have a collar (40) of even a slightly larger diameter.
