Restore a factory-tight seal between your pump motor and wet end with the Swimables SW-21-012 Seal Plate, machined to serve as a precise drop-in replacement for Pentair part 356012. This critical component forms the barrier that keeps pool water on the volute side and away from the motor, preventing costly leaks and premature motor failure. Molded from rigid, chemical-resistant material, it maintains dimensional stability even after years of exposure to chlorinated or salt-treated water. Whether you are rebuilding a pump or replacing a cracked original plate, the SW-21-012 delivers the exact fit and dependable sealing your Pentair SuperFlo or Pinnacle pump demands.

Key Benefits

• Pentair 356012 Drop-In Match: Mirrors the factory part dimensions for SuperFlo and Pinnacle pumps -- no trimming, drilling, or adapting needed.
• Watertight Motor Protection: Creates a reliable barrier between the pump volute and motor housing, stopping leaks that can destroy bearings and windings.
• Chemical-Resistant Material: Engineered to hold up against chlorine, bromine, and saltwater without warping, swelling, or becoming brittle.
• Accurate Alignment: Tight manufacturing tolerances ensure the shaft seal seats correctly and the diffuser gasket compresses evenly for consistent performance.
• Extends Equipment Life: A properly sealed plate prevents water intrusion into the motor cavity, safeguarding your investment and avoiding expensive repairs.
