FAQs

What is the primary use of this thread chaser?

Its primary use is to clean and repair the M12 x 1.25 threads found on many automotive Oxygen (O2) and Exhaust Gas Temperature (EGT) sensors.

What material is the thread chaser made from?

It is manufactured from chrome molybdenum with a Titanium Nitride (TiN) coating for enhanced durability.

What is the total length of this chaser?

The total length of the M12 x 1.25 thread chaser is 55mm.

What should I use with the thread chaser for best results?

It is recommended to use axle grease with the thread chaser. This lubricates the threads, aids in cleaning, and helps capture removed metal particles.

Can this chaser be used on other thread sizes?

No, this specific chaser is designed only for M12 x 1.25 threads. Other sizes (M14 x 1.5 to M22 x 1.5) are available separately.

How do I clean the thread chaser after use?

After use, remove the axle grease and debris, then wipe the chaser dry and store it in a clean, dry place.

Which vehicle brands are commonly compatible with this thread size?

This thread size is commonly found on sensors for brands including BMW, Mercedes-Benz, Nissan, Renault, Triumph, and Ducati, among others.

Troubleshooting

Chaser is difficult to turn

Ensure sufficient axle grease is applied and that the threads are not excessively damaged. If threads are severely damaged, the chaser may not be able to repair them fully.

Metal particles remain in the port after use

Ensure sufficient axle grease was used to capture debris. Carefully clean the port with a shop rag. Avoid blowing compressed air directly into the port, as this can scatter debris.

Chaser does not clean threads effectively

Verify that the thread size is M12 x 1.25. Check that the chaser itself is clean and undamaged. Ensure consistent turning pressure.
