OEM Polaris 39-300 Water Management System Assembly with O-Ring is a replacement part engineered for the Polaris 3900 Sport and P39 pool cleaners. It uses water pressure from the return line to drive three internal jets, generating a vortex that draws debris into the cleaner’s super bag. The included O-ring provides a watertight seal, preventing leaks and ensuring full efficiency. Made from durable materials, this assembly is key to maintaining powerful suction and optimal cleaner performance.
