About This Item
The Pentair Diffuser O-Ring (356190Z) is the OEM replacement sealing O-ring for the diffuser assembly on the IntelliFlo3 and IntelliPro3 Variable Speed and Flow pool pumps.
The diffuser O-ring seals the joint between the diffuser and the pump housing, maintaining the hydraulic pressure differential that drives water through the impeller. A degraded or displaced O-ring at this location allows air ingestion and pressure loss, reducing pump efficiency and potentially causing the pump to lose prime. Replacing this O-ring at the first sign of air in the system — or as part of any routine diffuser service — restores the sealed flow path the pump depends on. Fits both the 1.5HP and 3.0HP configurations of the IntelliFlo3 and IntelliPro3 series.
