ON/OFF TOOL

The DURA On/Off Tool is efficient and easy to use. To latch or lock the tool, the sucker rod string is lowered onto the valve rod or sucker rod already in the well. The tool will engage correctly with the rods since the tool is self-aligning. By setting the weight of the sucker rod string on the tool it will latch and lock on the rod. By lifting the rod string the rig crew will be able to tell if the plunger is attached. If it does not latch set the rod string back down on the tool and slowly rotate the rods to the left. This will help to line up the on-off tool body and tang. Once properly aligned, the tool will latch with the weight of the rod string. This process may have to be repeated several times if the on-off tool will not latch. To release the tool, lower the pump or plunger to the top or bottom of the stroke and then turn the rods to the RIGHT (left-hand tools are available on special order).

To release a left-handed tool the procedure is the opposite of a right-handed tool. New left-handed tools are marked with red tape and have “L.H.” stamped on the wrench flat.

They are available in a number of sizes, light, medium and heavy duty, and as a right or left hand release.
