Even minor contamination at the joint can prevent the clamp from achieving a full pressure seal. Torque all hardware fasteners evenly in an alternating pattern to distribute clamping force uniformly around the tank circumference.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-22 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":54303478120723,"sku":"DEX2421JKIT","price":379.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-clamp-system-with-seal-hardware-and-labels-for-swimclear-cartridge-filters-and-progrid-de-fi-2.webp?v=1783429699","url":"https:\/\/poolaroo.com\/products\/hayward_dex2421jkit","provider":"Poolaroo","version":"1.0","type":"link"}
