  • Patent number: 7870655
    Abstract: A method for endforming a tubular member for use assembly for a hydraulic system comprises (1) a connector member having an inner surface exhibiting a stepped configuration and a fixing member at the distal end thereof, and (2) an endform tubular member having an outer surface corresponding to the inner surface of the connector member, wherein the endform tubular member mates with inner surface of the connector member to provide an endform tubular assembly having an improved design for conveying fluids in a hydraulic system. The endform tubular assembly has inherent features therein that are measured to provide quantified values for assessing the robustness of the assembly and predict the performance of such assembly in high pressure applications for prolonged periods of time.

  • Patent number: 7581760
    Abstract: An endform connector having an axial bore through which a fluid is conveyed comprising: a rigid tubular member having a first terminal end, a second terminal end, a channel having an inner diameter extending from the first terminal end to the second terminal end through which a fluid is transported, a stem portion extending a fixed distance from the first terminal end, and at least one sealing member extending radially outward from the stem portion forming a radially increasing surface having a tapered profile terminating in a rim, which exhibits an ellipsoidal perimeter, adapted to be inserted into an inner channel of a fluid transport hose; wherein the endform connector is sealed to the fluid transport hose; and, a connector portion on the second terminal end adapted to be coupled with a fluid conveying structure.
