Product Information
Full details
This Laser Tools NOx Sensor Tap Set is essential for mechanics working on modern diesel vehicles, particularly those from Ford EcoBlue, Mercedes-Benz, and Vauxhall/Opel. It provides precise M20x1.5 and M22x1.5 thread cleaning and re-tapping capabilities for NOx sensors, ensuring proper installation and function. A key benefit is the durable TiN coating that extends tool life. One caveat is that it is not suitable for Ford fuel vaporiser applications, which require a different part number.

FAQs
What vehicles is this NOx Sensor Tap Set compatible with?
This set is designed for NOx sensors on vehicles like Ford EcoBlue, Mercedes-Benz, and Vauxhall/Opel, featuring M20x1.5 and M22x1.5 threads. Always check your vehicle's specifications.
What is the purpose of the TiN coating?
The Titanium Nitride (TiN) coating increases the hardness and wear resistance of the tap, extending its service life and improving its cutting performance.
Why should I use axle grease with these taps?
Axle grease lubricates the tap, reduces friction, and, most importantly, traps metal shavings in the tap's flutes. This prevents debris from entering the exhaust system and ensures cleaner threads.
Can I use this set for Ford fuel vaporisers?
No, this set is specifically for NOx sensors. For Ford fuel vaporiser applications, you need Laser Part No. 8332.
How do I clean the taps after use?
Wipe away all grease and metal debris immediately after use. A cleaning solvent may be helpful. Store in a dry place to prevent rust.
What are the thread sizes included in the set?
The set includes taps for M20x1.5 and M22x1.5 threads.
What is the total length of each tap?
Each tap in the set has a total length of 48mm.
Troubleshooting
Tap is difficult to turn or seems stuck.
Ensure you are using sufficient axle grease. Withdraw the tap slightly (counter-clockwise) to clear debris. Check that the threads in the port are not excessively damaged or cross-threaded before attempting to tap.
Metal shavings are not being captured in the flutes.
Ensure you are using a quality axle grease and applying it liberally to the tap. Clean the tap flutes thoroughly; they may be clogged. Make sure you are withdrawing the tap periodically to allow debris to exit.
Tap does not seem to be cutting new threads.
Verify you are using the correct tap size for the thread. Ensure the tap is inserted straight and not at an angle. The threads in the port may be too damaged for this tap to repair effectively.
Tap appears to be getting dull quickly.
Ensure proper lubrication with axle grease. Avoid forcing the tap. The material of the threaded port might be exceptionally hard, or the tap may have been used inappropriately on incorrect materials.
Pros and Cons
Pros
- Durable and long-lasting due to TiN coating and chrome molybdenum construction.
- Covers two common NOx sensor thread sizes, increasing versatility.
- Helps ensure proper installation and sealing of NOx sensors.
- Designed to minimize thread damage and contamination during use.
Cons
- Not suitable for Ford fuel vaporiser applications (requires Laser Part No. 8332).
- Requires proper use of axle grease to function optimally and prevent debris.
- May require additional tools for sensor removal and installation.
Setup, Compatibility & Care
Compatibility:
- This set is specifically designed for cleaning and re-tapping threads on NOx sensors.
- Compatible with M20x1.5 and M22x1.5 thread sizes.
- Primarily intended for use on Ford EcoBlue, Mercedes-Benz, and Vauxhall/Opel vehicles, but may fit other applications with the same thread sizes.
- Note: For Ford fuel vaporiser applications, use Laser Part No. 8332.
Setup & Use:
- Identify the correct tap size (M20x1.5 or M22x1.5) for the NOx sensor thread.
- Apply a generous amount of axle grease to the flutes and cutting edges of the chosen tap. This helps lubricate the cutting action and traps metal shavings.
- Carefully insert the tap into the NOx sensor port.
- Slowly rotate the tap clockwise to cut or clean the threads. Apply steady, even pressure.
- Periodically withdraw the tap slightly (counter-clockwise) to clear accumulated debris from the flutes.
- Once clean threads are achieved, remove the tap.
- Clean the tap thoroughly after use.
Care:
- Always clean the taps immediately after use. Remove all grease and metal debris.
- Store the taps in a dry environment to prevent corrosion.
- Inspect taps for wear or damage before each use. Discontinue use if excessive wear is apparent.
