Pentair Strainer Cover O-Ring 5" | U9-229Z

Genuine Pentair 5" strainer cover O-ring. Prevents air leaks, maintains prime, and ensures efficient pump performance.

Features

• Provides a tight seal between strainer lid and housing.
• Prevents air leaks that affect pump priming.
• Durable Buna-N material resists pool chemicals.

Description

The Pentair Strainer Cover O-Ring U9-229Z is a critical sealing component designed to maintain a watertight connection between the pump lid and strainer housing. A worn or damaged O-ring can allow air to enter the system, leading to poor suction, reduced efficiency, and difficulty maintaining prime.

This OEM 5-inch O-ring is built from durable elastomer material to withstand chemical exposure and constant pressure cycles. It restores proper sealing performance, helping your pump operate efficiently and reliably across a range of Pentair Sta-Rite pump models.

Pro Tip

Always lubricate the O-ring with a silicone-based pool lube before reinstalling the lid. This improves sealing, prevents binding, and extends gasket life.

Installation Tips

Turn off power before opening the pump. Clean the groove and lid surface thoroughly. Seat the O-ring evenly and avoid twisting to ensure a proper seal.
