Apply a silicone-based lubricant — never petroleum-based products — to each O-ring prior to seating. Browse our \u003ca href=\"https:\/\/poolaroo.com\/collections\/pool-plumbing-lubricants\"\u003ePool Plumbing Lubricants\u003c\/a\u003e for a compatible option. A properly lubricated and fully seated O-ring is critical to preventing leaks at the header under operating pressure. Heater header service must be performed by a licensed pool professional or qualified HVAC technician.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-22 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":54303483756819,"sku":"FDXLFOR1930","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-header-o-ring-kit-for-fd-heaters-fdxlfor1930.webp?v=1786347306","url":"https:\/\/poolaroo.com\/products\/hayward_fdxlfor1930","provider":"Poolaroo","version":"1.0","type":"link"}
