Features

• OEM Pentair 2-231 Buna-N 70 diffuser O-ring.

• Helps prevent air leaks and priming issues.
• Durable, chemical-resistant rubber construction.

Description

A worn diffuser O-ring can lead to air leaks, poor pump priming, and reduced system efficiency. The Pentair 39006600 is an OEM 2-231 Buna-N 70 O-ring designed to restore a proper seal between the diffuser and pump housing.

This durability-focused replacement helps maintain consistent suction, proper flow, and overall pump performance. It is a simple but critical component in keeping your pool system operating efficiently.

Pro Tip

If your pump is struggling to prime, inspect all O-rings in the system. Replacing multiple worn seals at once often resolves air leak issues completely.

Installation Tips

Turn off power and relieve pressure before servicing. Clean the sealing surface, lightly lubricate the O-ring with pool-safe silicone lubricant, and ensure it seats evenly to avoid pinching during reassembly.
