Pool Pump Diffuser O-Ring – For Quality Superflo, Earthco & Aquamax Pumps

The Pool Pump Diffuser O-Ring is a critical sealing component that fits between the pump body and diffuser on Quality Superflo, Earthco (EQ), and Aquamax swimming pool pumps.

This O-ring ensures a tight seal that allows the pump to prime efficiently and operate at full performance.

Without this O-ring in place, your pool pump may struggle to draw water properly, leading to reduced suction, air leaks, or system inefficiencies.

 Whether you're servicing or rebuilding your pump, replacing the diffuser O-ring is essential to restoring correct pressure and flow.

This is a genuine replacement part manufactured for long-lasting durability and chemical resistance in harsh pool environments.

Key Features:

• Genuine O-ring for Quality Superflo, Earthco (EQ), and Aquamax pool pumps

• Fits between the pump body and diffuser to ensure airtight sealing

• Prevents priming issues and loss of suction

• Essential for pump efficiency and proper circulation

• Durable, chemical-resistant rubber construction

• Easy to install during pump servicing or diffuser replacement

• Suitable for residential and commercial pool pump systems

A missing or worn diffuser O-ring can prevent your pool pump from priming correctly—replace it during routine maintenance to avoid performance issues.
