Hayward HCP/HCP4000 Diffuser O-Ring | HCXP338V60
Maintain the high-pressure efficiency of your commercial pump with the Hayward HCXP338V60 Diffuser O-Ring. This genuine OEM replacement seal is designed specifically for Hayward HCP and HCP4000 series commercial pumps. It creates the critical airtight and watertight seal between the pump diffuser and the pump housing (volute), ensuring that water is forced through the impeller and out the discharge port rather than recirculating inside the housing.
In commercial 3-phase pump systems, even a minor seal failure can lead to "internal bypass," which causes the pump to lose pressure, run hotter, and consume more energy. Replacing a flattened or brittle O-ring with this factory-authorized part restores the hydraulic integrity required for large-scale water circulation and filtration.
