The Pentair U9-228AZ Seal Plate O-Ring forms a tight, reliable seal that keeps your Pentair pump running smoothly and leak-free. Additionally, this high-quality replacement O-ring maintains strong compression, resists chemical wear, and restores efficient system pressure. Moreover, installation is easily and gives your pump the long-term reliability you expect from Pentair.

What does the Pentair U9-228AZ Seal Plate O-Ring do in a pool pump?

This O-ring sits between the seal plate and the pump housing to create a watertight seal that protects your motor and internal components. Furthermore, as the seal wears or flattens, small leaks appear and pump performance drops. Specifically, replacing it with the U9-228AZ restores proper suction, protects your pump, and keeps your system running efficiently with less strain.

Expert Pentair Parts Insight

A worn or flattened seal plate O-ring is one of the most common causes of slow leaks, air intrusion, and loss of prime. Moreover, always inspect the O-ring any time you service the pump seal or remove the seal plate. Additionally, lubricate lightly with a silicone-based lube during installation for the best fit and compression.

How do I know if I need to replace the U9-228AZ seal plate O-ring?

You should replace this O-ring any time you see moisture around the pump seam, hear the pump struggling to prime, or notice air bubbles returning to the pool. Additionally, these symptoms usually indicate a flattening or chemical-worn seal. Moreover, a new U9-228AZ restores a clean, even compression seal that protects both the motor and the mechanical seal.

Pro Tip: If you’re already replacing the pump seal, always replace the seal plate O-ring at the same time. Furthermore, this will prevent repeated leaks and saves you from reopening the pump later.
