ABSTRACT:
Mechanism for attaching a high pressure tube to an opening in a housing using a tapered opening into which a high pressure tube is inserted. A fitting has one end positioned about the tube end and is then press fitted not only to the housing on an outer diameter fitting section but also inwardly against the tube end as well as the other fitting end being press fitted to the housing to further secure the fitting to the housing, all of the press fits providing high pressure seals. The fitting other end also provides for prealignment of a fitting cross passage with a housing side passage so that high pressure fluid flowing between the tube and the side passage has minimal directional change in passing from the cross passage to the side passage. The fitting other end is adapted to receive press fitting force in axial alignment with the fitting.
