Description
Maytronics Ultra Fine Filter Kit S300 4-Pack
The Active Brush Bushing S300 (Part 9991467-R4) is a genuine OEM replacement bushing designed for the active brush drive system in many Maytronics/Dolphin robotic pool cleaners. It supports the brush spindle, helps reduce wobble or play, and ensures smooth rotation of the active scrubbing brush.
Key Features
Precision-engineered bushing made to the original specifications for proper fit and alignment.
Helps restore brush stability by providing a secure bearing interface for the brush drive—reduces wobble and helps maintain efficient scrubbing.
Built for pool-environment durability: capable of handling water, pool chemicals, and repetitive motion cycles.
A targeted repair part: instead of replacing the entire brush drive or motor, this bushing offers a cost-effective maintenance option.
