Hailea HAP-120 Air Pump Replacement Diaphragms (Pair)

Restore the high-volume performance of your aeration system with the Genuine Hailea HAP-120 Replacement Diaphragms. Designed specifically for the HAP-120 Hi-Blow Linear Air Pump, these diaphragms are the critical internal components responsible for generating the 120L/min output your system requires. Over time, heat and constant oscillation cause standard rubber to lose elasticity or tear, resulting in a noticeable drop in air pressure.

Fabricated from a specialized, high-grade artificial rubber, these replacement diaphragms offer superior durability and resistance to ozone and environmental wear. Replacing your diaphragms is a cost-effective alternative to purchasing a new unit and is recommended as part of an annual maintenance schedule for 24/7 aeration environments like koi ponds, large aquaria, and hydroponic systems. Ensure your livestock receives the oxygen levels they need with these precision-molded factory originals.
