Abstract
A high pressure flex fitting comprises a tube assembly which engages within a fitting body. The tube assembly comprises a tube upon which a deformable flanged compression sleeve is disposed adjacent an elastomeric sealing ring which in turn is adjacent a retainer ring, the retainer ring being seated adjacent a flared end of the tube. A nut having an end flange engages over the sleeve and the flange on the nut bears against the radial flange on the sleeve, pushing the sleeve on the tube into the fitting body when the nut is threadedly engaged onto the fitting body. The fitting body includes a large cavity, within which the flared end of the tube is suspended, have a tapered inner entrance section from an entrance diameter larger than the sleeve to an inner diameter smaller than the sleeve to completely fill the area between the cavity wall and the tube adjacent the sealing ring which effects the seal between the cavity wall and the tube to prevent extrusion and fracturing thereof.
