If you are working from a parts breakdown, match the ECX176865 number rather than the description, since a filter carries more than one nut.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSmall hardware, real job\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eRetainer hardware inside a DE filter lives in warm, chlorinated, DE laden water. Threads corrode, nuts strip, and a nut that no longer holds lets the assembly move. Once the internals shift, the grids no longer seat the way they should and DE starts coming back through the returns. It is a cheap part to replace while the filter is already open, and an annoying reason to open it again if it is skipped.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48633645662420,"sku":"HAY-051-1855","price":7.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_3510e41e-5ec5-440e-ba27-0105a10a119f.png?v=1788808252","url":"https:\/\/www.activepoolsupply.com\/products\/retainer-nut","provider":"Active Pool Supply","version":"1.0","type":"link"}
