When it is time to fit the new one, tighten it snug rather than hard: it is pulling the rim onto a gasket, and overdriving it can distort the rim and undo the seal you were trying to restore.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48633932873940,"sku":"HAY-301-2085","price":21.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_58f9f52f-0394-4cfe-8400-ba0ea45d7954.jpg?v=1788817577","url":"https:\/\/www.activepoolsupply.com\/products\/light-retainer-screw-kit","provider":"Active Pool Supply","version":"1.0","type":"link"}
