Abstract:
To provide a fitting assembly that is configured to assist in separating two or more fitting components during disassembly of the fitting.
A fitting assembly 10 is provided with a first fitting component 14 having a stepped wall surface; and a second fitting component 12 radially spaced from the first fitting component 14 when the fitting assembly 10 is in a finger tight condition prior to final tightening. When the second fitting component 12 is displaced into contact with the stepped wall surface during final tightening of the fitting, the stepped wall surface assists in separating the first fitting component 14 from the second fitting component 12 upon fitting disassembly.
