A fitting seated against a compromised tank surface will not seal reliably regardless of how tightly it is torqued. If the tank body shows structural damage at the fitting port, the tank itself will require replacement.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-22 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":51774185177363,"sku":"ECX4201CA","price":81.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/HPPECX4201CA_0.jpg?v=1747703033","url":"https:\/\/poolaroo.com\/products\/hayward-tank-fitting-ecx4201ca","provider":"Poolaroo","version":"1.0","type":"link"}
