Thread Chaser Tap Set for Exhaust Sensor Thread Repair

A compact thread chaser tap set for cleaning up and recutting damaged or rusted exhaust sensor threads. Used on probe fittings where threads have seized, corroded or become worn, it helps prepare the thread so the sensor can be refitted properly without forcing it back in.

Useful for exhaust work, vehicle maintenance and workshop repairs, especially when dealing with NOX sensor and particle filter sensor threads underneath a vehicle. The short pattern suits areas where access is awkward and larger tooling can be difficult to turn, making it a practical option when working around tired exhaust parts or seized fittings.

The set includes two common thread sizes for exhaust sensor repair: M20 x 1.5 and M22 x 1.5. A guide bolt is included to help keep the tap running true as you work, while the cleaning grooves help clear debris from the thread during recutting. The 6 cutting edges assist with centring, and the external hexagon drive gives a more secure way to apply force in tighter spaces. For regular servicing work, it is a useful thread repair set to keep close to hand when awkward exhaust sensor jobs come up.
