ABSTRACT:
A deformation indicator is disclosed for repeatably adjusting the fasteners on a flange assembly to maintain a leak-free joint. The indicator is mounted on one of the fasteners used for fastening together the flange members, and extends to a predetermined distance from the adjacent flange member. When the flange fasteners must be adjusted to account for creep in the packing material in the flange, they are adjusted to restore the distance between the indicator and the adjacent flange member to the predetermined value.
