ABSTRACT:
A torque applying tool with a removable adaptor for actuating an underground valve of a fluid-carrying conduit, such as a water main, gas line, petroleum pipeline, etc. The adaptor has a hollow cylindrical sleeve for receiving an elongate rod of a T-bar tool, the rod and the sleeve being removably connected to each other by a bolt. The adaptor of the T-bar is configured to engage with a socket tool for application of torque to a valve, the adaptor including a nib shaped to closely fit within an opening in the socket tool. To prevent the socket from sliding off the adaptor during use, an optional spring loaded detent is provided on the adaptor to retain the socket in releasable connection with the T-bar.
