发明名称 Plumbing tool for temporarily plugging a pipe
摘要 The invention is directed to a plumbing tool for temporarily plugging a pipe which normally contains fluid or gas under pressure. The plumbing tool includes an elongate threaded rod having proximal and distal ends. A hollow elongate sleeve is disposed around the threaded rod. Similarly, a cylindrical gasket is disposed around the rod between the hollow sleeve and a gasket stop located at the distal end of the elongate rod. The plumbing tool further includes an arcuate handle extending proximally from the proximal end of the elongate threaded rod. The arcuate handle is configured to include a radius sufficiently great to permit valves to be telescopically communicated along the entire length of the arcuate handle and along the length of the hollow elongate sleeve.
