A worn or flattened O-ring at the tank closure is the most common cause of pressure-side leaks on Star-Clear Plus filters. Tighten the closure plate evenly and in a cross-pattern where applicable to avoid distorting the sealing surface and to maintain even compression across the O-ring.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-22 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":51774149624083,"sku":"CX3020DA","price":92.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-top-closure-plate-for-star-clear-plus-cartridge-filters-c3020-c4020-cx3020da-1.webp?v=1787908361","url":"https:\/\/poolaroo.com\/products\/hayward-c3020-4020-top-closure-plate-cx3020da","provider":"Poolaroo","version":"1.0","type":"link"}
