30 day returns · Easy, with prepaid labels provided
Quick overview
- Genuine Hayward Factory OEM part ECX360JN, not a hardware store substitute.
- Metal construction Made of metal so it holds torque on a clamp that gets opened every cleaning cycle.
- Perflex DE filter The clamp sleeve nut used on the Hayward Perflex filter clamp assembly.
- Small part, big job The clamp is what seals the filter halves together, so worn nut threads turn into leaks.
- Cheap insurance Replace it while the filter is already open rather than chasing a drip later.
- Sold individually One nut per order, so count what your clamp assembly needs before you buy.

Product details
The Hayward ECX360JN is the clamp sleeve nut used on the Perflex DE filter clamp assembly. It is the genuine Hayward part, made of metal.
Why it wears out
The clamp is what pulls the filter body together and holds the seal. On a Perflex that means the fastener is loosened and retightened every time the filter is opened for service, and threads that have been cross threaded, corroded or rounded off will not pull the clamp down evenly. That shows up as a slow drip at the clamp line, or a clamp that will not tighten no matter how far the nut turns.
Before you order
This listing covers one nut. Look at the clamp assembly on your filter and count what you need, then replace the hardware while the filter is already apart rather than opening it a second time.
