ABSTRACT:
A fitting assembly is provided with a first fitting component having a stepped wall surface; and a second fitting component radially spaced from the first fitting component when the fitting assembly is in a finger tight condition prior to pull-up. When the second fitting component is displaced into contact with the stepped wall surface during fitting pull-up, the stepped wall surface assists in separating the first fitting component from the second fitting component upon fitting disassembly.
