Mueller-Kueps 506027 Sensor Tap Kit with Ratchet Wrench M12x1.25, M14x1.5, M16x1.5

The Mueller-Kueps 506027 Sensor Tap Kit is a professional-grade thread restoration kit designed for mechanics working on diesel exhaust systems. This comprehensive 7-piece kit covers three common metric thread sizes — M12x1.25, M14x1.5, and M16x1.5 — and includes a compact ratchet wrench, making it a complete solution for restoring damaged or burnt sensor threads right out of the box.

Engineered to professionally restore damaged threads on NOx sensors, temperature sensors, oxygen sensors, and diesel particulate filters (DPF), this kit allows technicians to recut corroded or seized sensor holes without removing or damaging the exhaust system. The ultra-short tap design with an integrated guide pin ensures precise centering and damage-free thread restoration, even in extremely tight and hard-to-reach spaces.

Key Features:

• Extra-Short Design: Ultra-compact tap length allows use in confined engine bays and tight exhaust system locations
• Integrated Guide Pin with Cleaning Grooves: Removes coarse carbon deposits while guiding the tap for accurate, centered recutting
• Hard Material Protective Coating: New advanced coating extends tool life and improves performance on hardened or corroded threads
• Six Cutting Edges: Provides ideal centering and efficient thread restoration
• Includes Compact Ratchet Wrench: Everything needed to complete the job is included in one kit
• Three Thread Sizes Covered: M12x1.25, M14x1.5, and M16x1.5 — the most common sizes for NOx and temperature sensors
• Universal Application: Suitable for both light-duty and heavy-duty diesel engines
• Made in Germany: Professional quality manufacturing backed by Mueller-Kueps' reputation for precision tooling

The Mueller-Kueps 506027 is the preferred choice for professional diesel technicians who need a reliable, compact sensor thread restorer kit that gets the job done without collateral damage to expensive exhaust components.
