Sensor Tap M16 x 1.5 - Mueller - Kueps

Part #: 506 516

The Mueller-Kueps Sensor Tap M16 x 1.5 (Model 506 516) is a specialized professional tool designed for the precise repair of damaged M16 x 1.5 threads, particularly in NOX sensor mounting holes. This sensor tap provides a cost-effective alternative to replacing entire NOX sensors, allowing technicians to restore compromised threads with accuracy and efficiency. Its robust, professional-grade construction ensures reliable performance in demanding automotive and industrial repair environments.

Key Features

  • Precision Thread Repair: Specifically engineered for M16 x 1.5 threads, providing an exact fit for NOX and temperature sensor applications.
  • Integrated Guide Pin: Features a unique integrated guide pin that ensures straight insertion, significantly reducing the risk of cross-threading or further damage to the sensor port or the sensor itself.
  • Cost-Effective Solution: Enables the professional restoration of damaged threads, eliminating the need to purchase a new, expensive NOX sensor solely due to compromised mounting threads.
  • Professional-Grade Durability: Manufactured by Mueller-Kueps, a renowned German innovator in automotive tools, this tap is built for longevity and consistent performance under rigorous use.
  • Extra-Short Design: The extra-short tap body allows access to tight sensor bosses with limited clearance, facilitating repairs without removing nearby components.
  • Universal Application: Suitable for universal use on both light- and heavy-duty diesel engines.

Applications

The Mueller-Kueps Sensor Tap M16 x 1.5 is an indispensable tool for professional technicians and mechanics working on a variety of vehicles and industrial equipment. It is primarily used for:

  • Repairing burnt, carbon-packed, or lightly damaged threads in NOX, temperature, and particle filter sensor ports.
  • Cleaning up cross-threaded sensor holes after sensor removal.
  • Prepping threads before installing new sensors to ensure proper torque and seal.
