NOx Sensor Port Thread Chaser M22 x 1.5mm Repair Tool

A NOx sensor port thread chaser used to clean up and repair damaged M22 x 1.5mm threads before a sensor is refitted. It is intended for restoring sensor port threads to a usable condition, helping reduce the chance of cross-threading when fitting a replacement sensor.

Used for exhaust and emissions work, this tool is handy when dealing with seized, dirty or slightly damaged sensor threads during vehicle maintenance and servicing. Common applications include Mercedes-Benz and Vauxhall/Opel NOx sensor ports, making it useful for garages, mobile mechanics and anyone carrying out repair work before installing a new sensor. It can also be used on other M22 x 1.5 threads where the existing thread needs tidying up before refitting.

The M22 x 1.5mm size matches the stated thread type, so it is suited to thread cleaning and repair where that size is required. A 22mm socket or spanner can be used to drive the chaser, which keeps setup straightforward without needing any special adaptor. The rubber O-ring helps hold the chaser in place in the socket or spanner, which can be useful when access is awkward or when working underneath the vehicle. For regular sensor replacement and thread preparation, it is a practical way to sort damaged threads before a new part goes in.
