Hayward ECX12866 PerFlex DE Filter Gauge Port Adapter EC65 EC75

The Hayward ECX12866 is a genuine OEM gauge and inspection port adapter designed for Hayward PerFlex Extended-Cycle D.E. pool filters. This critical replacement part allows you to easily install a standard pressure gauge or access the inspection port on the filter head, ensuring accurate pressure monitoring and preventing air intrusion.

🚩 PRO TIP

Monitor your filter's pressure gauge regularly — a reading 8–10 PSI above the clean starting pressure is your signal to backwash or clean the filter elements. Replacing a damaged gauge port adapter promptly prevents air intrusion and maintains accurate pressure readings for optimal filtration performance.
