Description
Maintain rock-solid impeller attachment in your Pentair pump with the OEM 355389 locking screw, a factory-original fastener built for SuperMax, Challenger, and SuperFlo pump platforms. This small but critical part prevents the impeller from loosening during operation, safeguarding against vibration-related performance drops and potential internal damage. Constructed to endure years of continuous cycling, the 355389 locking screw is an indispensable component whether you are performing scheduled upkeep or addressing a specific repair.
