Abstract:
1. A fitting assembly having a longitudinal axis, comprising: a fitting body that receives a conduit, a threaded drive nut comprising a drive surface and a first tapered longitudinal surface and a second tapered longitudinal surface; said first tapered longitudinal surface and said second tapered longitudinal surface being radially and axially outward of said radial drive surface, a first conduit gripping member and a second conduit gripping member, said first conduit gripping member will engage a camming surface of said fitting body during fitting pull-up, and said second conduit gripping member will engage said drive surface during fitting pull-up; said first conduit gripping member being radially spaced from said first tapered longitudinal surface when the fitting assembly is in a finger tight condition, wherein said first conduit gripping member is radially displaced into contact with said first tapered longitudinal surface during fitting pull-up of the fitting assembly onto the conduit, said first tapered longitudinal surface and said second tapered longitudinal surface assist in separating said drive nut from said first conduit gripping member and said second conduit gripping member during fitting disassembly, wherein said first tapered longitudinal surface and said second tapered longitudinal surface are discontinuous with respect to each other.
