Abstract:
1. A fitting assembly, comprising: a metal fitting body having a metal conduit capture surface tapered radially outward towards an axially outer end of the metal fitting body, and a stepped wall surface discontinuous with the metal conduit capture surface; and a metal conduit radially spaced from the stepped wall surface when the fitting assembly is in a finger tight condition prior to pull-up, an end portion of the metal conduit being in contact with the conduit capture surface when the fitting assembly is in a finger tight condition prior to pull-up, wherein during fitting pull-up a portion of the metal conduit is radially displaced into contact with the stepped wall surface with an axial component of an elastic reaction force against the conduit for separating the metal fitting body from the metal conduit upon fitting disassembly; and wherein the stepped wall surface extends from the tube capture surface to an axially outer camming mouth and tapers radially outward.
