A clean, undamaged mating surface is essential for a leak-free seal at operating pressure. If the existing O-ring or gasket shows any cracking or deformation, replace it at the same time to avoid a repeat service call.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-22 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":51774150082835,"sku":"ECX5000BP","price":250.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/HPPECX5000BP_0.jpg?v=1747701275","url":"https:\/\/poolaroo.com\/products\/hayward-filter-head-w-vent-valve-ecx5000bp","provider":"Poolaroo","version":"1.0","type":"link"}
