A spectacle blind flanges is a combination of a ring spacer and single blind. They are usually permanently installed in a piping system and rotated as needed. With space, weight, and other pipeline requirements permitting, it may be more convenient and cost-effective in specific situations to use a Spectacle Flange, which is a combination of the two that can be rotated to function as Single Blind or a Ring Spacer.
