Tyre Pressure Monitoring Sensor (RDK) Nut Set
Sold as a pair - 1 pair required per wheel
High-quality replacement nut set designed for the tyre
pressure monitoring system (RDK) fitted to Porsche 928 models from 1990
onwards.
Fits:
Diagram ref no 6
These vehicles were equipped with early-generation tyre
pressure sensors, with two sensors installed per wheel. During
removal—especially after decades in place—the original aluminium nuts often
deform or become unusable, particularly when removing sensors for wheel
refurbishment or powder coating.
This replacement nut set has been specifically developed to
allow correct reinstallation of the TPMS sensors, ensuring a secure fit
and proper system operation.
Manufactured with an anodized coating, these nuts offer significantly improved corrosion resistance compared to the original parts, making them ideal for long-term use.
Key Features
• Replacement nut set for Porsche 928 TPMS (RDK) sensors
• Suitable for models from 1990 onwards
• Designed for correct sensor reinstallation
• Anodized finish for enhanced corrosion resistance
• Ideal for wheel refurbishment and restoration
• Improved durability over original aluminium nuts
Function and Purpose
These nuts are essential for securing the tyre pressure sensors.
They help to:
• Fix TPMS (RDK) sensors securely within the wheel
• Ensure correct positioning and function of sensors
• Enable proper reinstallation after removal
• Maintain long-term reliability of the system
Why Replace TPMS Sensor Nuts
Original nuts are often compromised during removal.
Common issues include:
• Deformation during removal
• Corrosion after decades of use
• Loss of proper thread engagement
• Reduced sealing and fastening reliability
Even if original nuts appear usable, replacing them ensures correct fitment and long-term durability.
Perfect for Wheel Refurbishment
When refurbishing or powder coating wheels:
• Sensors must be removed
• Original nuts are often damaged or unusable
• New nuts are required for safe reinstallation
This kit provides the correct solution for restoration and refurbishment work.

Tyre Pressure Monitoring System (TPMS or RDK) Tool Set for
Nut and Sensor
This specialised TPMS fitting
tool set is designed specifically for the Porsche 928 S4, 928 GT and 928 GTS models
equipped with factory tyre pressure monitoring systems.
Fits:
Tools for diagram Ref No 19
Correct installation and removal of the original 928 RDK sensors requires the proper factory-style tools. Using incorrect tools can damage the sensor housing, securing nut or wheel assembly.
This complete set includes:
• Sensor nut tool with square pegs (for the retaining nut)
• Sensor body tool with round pegs (for the RDK sensor itself)
What This TPMS Tool Set Does
The Porsche 928 RDK system uses a two-part securing system
inside the wheel:
1 - A
retaining nut that secures the sensor assembly
2 - The
sensor body itself, which must be held or positioned correctly during
removal or installation
The square peg tool (Porsche part number 00072192740) engages precisely with the
sensor retaining nut.
The round peg tool (Porsche part number 00072192730) interfaces correctly with the RDK sensor body.
Together, they allow safe disassembly and reassembly without damaging rare and expensive components.
Why You Need the Correct 928 RDK Tools
Prevents Sensor Damage
Original Porsche 928 TPMS sensors are costly and increasingly hard to source.
Using the proper peg tools prevents cracking or distortion during removal.
Protects Wheel Finish
Improvised tools can slip, causing damage to alloy wheels. These tools ensure
precise engagement and controlled torque application.
Essential for Wheel Refurbishment
When refurbishing, powder coating or restoring Porsche 928 wheels, the RDK
sensors must be removed correctly. This tool set is essential for
professional-level work.
Ideal For
• Porsche specialist workshops
• Classic Porsche restoration projects
• Wheel refurbishment professionals
• 928 owners maintaining original RDK systems
• Safe sensor removal before powder coating wheels

OEMatch Tyre Pressure Monitor — Grip, Safety, Confidence
Tyre pressure monitoring on Porsche models is central to how the car feels on the road and how safely and efficiently it runs. OEMatch tyre pressure monitor components help maintain correct pressure feedback to the vehicle systems so you can keep your Porsche predictable, composed and reassuring in everyday use.
- Individual TPMS sensors and related components for Porsche applications
- Service parts to support maintenance of existing monitoring hardware
- Options suited to routine refreshes, wheel changes and refurbishment work
Understanding OEMatch Tyre Pressure Monitor
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original tyre pressure monitor. OE (Original Equipment) refers to parts matching original specifications for the tyre pressure monitor and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM tyre pressure monitor components engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. Many owners search for genuine or OEM tyre pressure monitor parts; these are direct-fit alternatives designed to match the original form, fit and function. Tyre pressure monitoring systems on Porsche vehicles use wheel-mounted sensors and valves to send pressure information to the control unit, warning you of under- or over-inflation. Over time, batteries within sensors age, sealing surfaces can deteriorate and external hardware is exposed to road debris, moisture and corrosion. OEMatch focuses on Porsche-related items such as tyre pressure monitor components to support keeping vehicles on the road for longer, across different generations.
- Help maintain consistent tyre pressures for stable handling characteristics
- Support fuel efficiency and even tyre wear by highlighting under-inflation
- Assist with compliance where TPMS functionality is required by regulation
- Reduce nuisance warning lights caused by ageing or faulty sensors
Why Tyre Pressure Monitor Wear and Fail
- Internal batteries within TPMS sensors reaching the end of their service life over time
- Exposure to moisture, salt and dirt leading to corrosion around valves and fixings
- Damage during tyre changes or wheel refurbishment if components are not handled carefully
- Age-related degradation of seals, grommets and other small service parts
- Changes to wheels or vehicle systems that leave older sensors incompatible
The Importance of Replacing with OEMatch Tyre Pressure Monitor
Replacing worn or faulty tyre pressure monitor components helps keep TPMS warnings meaningful, so genuine issues are not masked by persistent false alerts. Consistent monitoring supports the way a Porsche steers, brakes and rides by making it easier to keep tyre pressures where they should be. Updating ageing sensors or service parts can also contribute to avoiding slow leaks and air loss linked to deteriorated hardware. OEMatch components are designed for Porsche applications, supporting the aim of preserving the driving characteristics and everyday usability of the car.
- Made to original-spec dimensions for compatibility with Porsche wheels and systems
- Suitable for targeted repairs, routine maintenance or broader refurbishment work
- Provide a practical option when renewing hardware alongside new tyres or wheels
- Support long-term enjoyment and day-to-day dependability of Porsche vehicles
Support & Advice
Fitting TPMS components can appear straightforward but may involve procedures such as correct torque for valve hardware, sealing checks and system relearning. If you are unsure about handling tyres, wheels or sensor programming, consider using a professional with the right equipment. Recheck tyre pressures and monitor for leaks after any work on tyre pressure monitor components.
