Product details

The Hayward ECX4249 is a locknut made for the Hayward Perflex EC50C90 Extended-Cycle DE filter.

What it does

A locknut is built to resist loosening from vibration, typically through a nylon insert or a slightly deformed thread that grips the mating screw more tightly than a plain nut would. On filter head hardware like the EC50C90, that resistance to loosening helps keep the assembly sealed and secure over repeated use.

Fit and compatibility

The ECX4249 is sized for the Hayward Perflex EC50C90 Extended-Cycle DE filter. If your filter is a different Perflex model, confirm the part number against your equipment before ordering.

Before you order

The ECX4249 is sold individually, carries UPC 610377025287, and ships as a standard parcel item. If your filter head hardware kit calls for more than one locknut, order enough to finish the job at once.
