The Mueller-Kueps Line Sensor Wrench Kit, No. 457 720, is a dropforged kit suited for exhaust sensors, brake lines, power steering lines, NOX, exhaust temperature, oxygen sensors, and more. The kit includes sizes 13mm to 19mm and features a stepped flange for easier access to lines. One side of the wrench can be used for maximum torque while the side with the flex head can be used for narrow spaces. Both ends have an inner hex to avoid from slipping as easy. They also have an extra lip to provide more strength.
