OEM vs Aftermarket
Genuine Flex Parts vs Generic Replacements
Aftermarket carbon brushes might fit the housing, but the carbon compound, contact pressure and dimensions are rarely identical to OEM spec. Here is how they compare on the details that matter.

Questions
Frequently asked
Which Flex machines are these carbon brushes compatible with?
These brushes are compatible with the Flex L 3906 C and the Flex LW1202 L45F13. Always verify your machine model before ordering to ensure correct fitment.
How many brushes come in the pack?
The pack contains 2 carbon brushes - one for each side of the motor. Always replace both at the same time to ensure even wear and consistent performance.
What is the part number for these brushes?
The Flex part number is F443816. The brush designation is L26. Use these references when ordering replacements or checking compatibility with your machine's service manual.
How do I know when my carbon brushes need replacing?
Common signs of worn carbon brushes include heavy sparking at the brush holders, loss of power or speed, intermittent cut-outs, or unusual motor noise. If you notice any of these, inspect the brushes immediately. Continuing to run the machine on worn brushes can damage the motor armature.
Are these genuine Flex parts or aftermarket?
These are genuine original Flex spare parts. Using OEM brushes ensures the correct dimensions, contact pressure and carbon compound for your specific machine, which matters for both performance and motor longevity.
Can I install these brushes myself?
Carbon brush replacement is a relatively straightforward maintenance task on most Flex polishers, but it does require opening the machine housing. If you are not comfortable working on power tools, have a qualified service technician install them. Always disconnect the machine from power before starting any maintenance.
How often should carbon brushes be replaced?
Replacement intervals depend on usage intensity. In a professional detailing or body shop environment with heavy daily use, inspect brushes every few months. For hobbyist use, a yearly inspection is a reasonable starting point. Replace at the first sign of wear rather than waiting for failure.
Will fitting new brushes restore a machine that has been cutting out?
If the cut-outs are caused by worn carbon brushes, yes, fitting a new pair will restore normal operation. However, if the brushes are not the root cause - for example, if there is armature damage or a wiring fault - additional repairs may be needed. It is worth inspecting the brush holders and armature surface at the same time you replace the brushes.
