It supplies the seals for the header joint as a set.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen you need it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAny time the header comes off the heater, the o-rings that sealed it should be replaced rather than reused. Rubber that has spent a season compressed between hot metal faces takes a permanent set, and once it has, it will not seal reliably against a fresh clamping load. A header that still weeps after a repair is very often a reused o-ring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy it matters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWater escaping at the header does not stay outside the heater. It runs down inside the cabinet onto the burner tray and the control components, which turns a cheap seal into an expensive repair. Fitting the correct Hayward kit when the header is already open is the inexpensive path.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48628869038292,"sku":"HAY-151-0024","price":39.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_97db0cf0-80fa-4fe4-aeb6-64779e5183a0.jpg?v=1788756788","url":"https:\/\/www.activepoolsupply.com\/products\/fd-header-o-ring-kit","provider":"Active Pool Supply","version":"1.0","type":"link"}
