An inner sleeve is used in a tubing joint assembly with this inner sleeve having a lateral shoulder generally perpendicular to the axis of the sleeve and with this shoulder terminating in a sharp angled peripheral rib. A tube is telescoped over this inner sleeve. An outer sleeve may optionally be telescoped over the tube and the entire assembly inwardly compressed by two dies which have interdigitated teeth. This compresses the outer sleeve, where used, and compresses the tube onto the peripheral ribs of the inner sleeve. The interdigitated teeth on the dies assure complete compression all the way around the periphery of the tube onto the inner sleeve with a lateral shoulder being formed on the tube to act against the lateral shoulder on the inner sleeve and thus longitudinally retain together these parts. Also a fluid pressure tight seal is established primarily at the sharp angled peripheral rib and its junction with the inner wall of the tube. |
