Pentair 355619Z Seal Plate O-Ring
Part Number: 355619Z
Description
This O-ring is designed to create a watertight seal at the seal plate/bracket of select Pentair pump models. It helps prevent water leakage around the motor’s seal plate, ensuring reliable pump operation and prolonging the life of internal components.
Compatibility & Fitment
- Fits Pentair Pinnacle and SuperFlo inground pool pumps.
- Also compatible with certain Sta-Rite SuperMax pumps and Pentair Tagelus filter models requiring the 355619Z seal plate gasket.
- Used when the seal plate is removed for servicing or when you detect water seepage or leakage at the bracket area.
Features & Specifications
- Made of EPDM rubber material suited for pool water exposure.
- Inner diameter approximately 8 1/4″; thickness approx. 1/8″ for correct fit in the bracket groove.
- OEM Pentair part — ensures correct fit and performance versus generic substitutes.
Installation Notes
Shut off power to the pump and relieve system pressure. Disconnect the motor bracket and remove the old O-ring and any residue from the groove. Clean the sealing surface thoroughly. Install the 355619Z O-ring in its correct groove, ensuring no twists or kinks. Re-assemble the bracket, torque to manufacturer specifications, and restore power. Monitor for any leak around the seal plate during the next startup.
Maintenance Tip
Inspect the seal plate O-ring annually during your pump service or if you notice seepage at the bracket seam. Lightly lubricate with a pool-safe silicone lubricant before re-assembly. Replacing the O-ring when worn helps maintain proper pump sealing, reduces water intrusion, and avoids premature bearing or seal failure.
