The 29-pc NOx and Particulate Sensor Service Kit, No. 60525200, fromPichler Tools, is designed for the disassembly and assembly of NOx and particle sensors, and the renewal of the holding thread in the exhaust system. The kit ensures that the sensor can be unscrewed without being damaged. The duo sensor socket helps loosen the sensor using a socket spanner (22mm or 24mm) which is in close contact with the sensor hexagon. The 30mm actuating nut and spanner are friction-locked to the socket.
