Abstract
A mechanical joint tube assembly and method of creating the same is disclosed for providing an improved fluid fitting assembly. A fitting having a primary tapered bore is forced onto a tube that has a larger diameter. The tube is radially contracted in certain portions and is radially expanded in other portions of the fitting in order to create a plurality of compression seals. A collar of the fitting is crimped around the bead that is formed in the tube in order to provide an additional compression seal and means for retaining the tube within the fitting. Alternative forms of the primary bore in the fitting includes a hexagonal shaped configuration, a splined shaped configuration and a slotted collar configuration for enhancing retention of the tube within the fitting. A unique method of manufacturing is used to make these tube fitting assemblies.
