ABSTRACT:
A high pressure fluid fitting is provided for repeated connection and disconnection. The fitting includes a threaded nipple and a flanged nipple configured for abutting end-to-end mating with one another. A thrust bearing formed from a metal harder than the flanged nipple is positioned adjacent the flange and on the side thereof opposite the mating face of the flanged nipple. A coupling nut with an inwardly extending annular flange is disposed over the flanged nipple and is threadedly engageable with the threaded nipple. The flange of the coupling nut moves against the thrust bearing and urges the nipples into tight sealing engagement. The smoothness and hardness and chemical dissimilarity of the thrust bearing avoid galling and other friction related damage to the fitting, and hence lead to an extended life for the fitting.
