The NOx Sensor Thread Restorer is designed for universal use on both light-duty and heavy-duty diesel engines, allowing technicians to professionally repair damaged NOx sensor threads without removing or replacing the exhaust system. This tool helps eliminate cross-threading, saves time, and reduces expensive component replacement.

Featuring a precision alignment guide at the front of the restorer, it ensures accurate angle positioning during repair. The extra-short design allows use with a socket or ratchet spanner, making it ideal for tight or hard-to-reach spaces in modern exhaust layouts.

This NOx sensor thread repair tool can also be used on diesel particulate filters, catalytic converters, and other exhaust sensor ports. It is built to withstand demanding shop environments while restoring threads cleanly and safely.

Available in sizes M20 x 1.5 and M22 x 1.5, this Mueller-Kueps tool delivers reliable performance and helps make difficult jobs faster and easier.
