ABSTRACT:
A pipefitting engaging tool assembly includes a housing that has a bottom wall and a peripheral wall. A head is attached to the housing and has a circular opening extending therethrough. The opening is defined by an outer edge that has a slot therein continually extending around the outer edge. A ring member has an outer perimeter edge and an inner perimeter edge. The inner perimeter edge has a plurality of teeth attached thereto and extends inwardly of the ring member. The teeth are configured to engage a pipefitting. The ring member is positioned in the slot in the outer edge of the opening. A drive assembly is mounted in the housing and is mechanically coupled to the ring member to selectively rotate the ring member in a first direction or a second direction.
