Aumzong Replacement Filter Head for Hayward Perflex EC65/EC75 (D.E.CX11194AT) — Vent Valve, Reinforced Plastic

Aumzong D.E.CX11194AT is a direct-fit replacement filter head with a vent valve designed to replace the Hayward Perflex EC65/EC65A/EC75/EC75A top, restoring safe air release and reliable filtration for above-ground pools and spas.

When the original Perflex filter lid cracks, warps, or loses its venting ability, pool filtration performance and pump safety can suffer. This Aumzong replacement is molded from reinforced plastic to match the fit and function of the factory Hayward ECX11194AT/D.E.CX11194AT top. It recreates the correct flange, bolt pattern and integrated exhaust valve so installation is straightforward and filtration runs smoothly.

Will this Aumzong head fit my Hayward Perflex EC65 or EC75 filter?

Yes — the D.E.CX11194AT is manufactured to the same form factor and bolt pattern used on Hayward Perflex EC65, EC65A, EC75 and EC75A extended-cycle D.E. filters. Confirm your model number on the existing lid before ordering.

How easy is it to install the replacement filter head?

Installation is straightforward for anyone comfortable with basic pool maintenance. The unit slips into the existing housing and secures with the original clamps or bolts; no special tools or plumbing changes are required.
