ABSTRACT:
A flange tightening tool for use in securing a flange to a pipe. The tool has a base plate, a tightening hexagonal shoulder, two attachment openings, two quick release disconnect mechanisms and a rotating handle perpendicular to the tightening base plate. The hexagonal shoulder enables the tool to be used with a companion light weight wrench. The tool can also be used with an open end wrench or an adjustable wrench. A rotatable handle is attached to the hexagonal shoulder such that said handle is perpendicular to the face of a flange that is to be tightened and can be used to hold the tool against the flange. When the quick release disconnect mechanisms are depressed about the pivot pin the quick release disconnect mechanism detracts from the mounting members releasing the mounting member separating the base plate and the flange. The tool prevents over tightening since the flange cannot be tightened past the point where the pipe contacts the base plate. An adapter plate enables the tool to be used with an additional size of flange.
