Aqua One Air Pump Spare Diaphragm Twin Pack

The diaphragm is the primary wear component in a diaphragm-driven air pump. Over time it can harden, crack, or lose flexibility, leading to reduced airflow, increased noise, or a noticeable drop in air pressure. Replacing the diaphragm at the first sign of these symptoms restores the pump to full performance and is considerably more economical than replacing the entire unit. Genuine Aqua One parts ensure the correct fit, material specification, and performance standard for the pump it is designed for.

Compatible with the Aqua One Precision 2500, Precision 7500, and Infinity AP250 air pumps. Supplied as a 2 pack. Easy to install without tools.
