It is the seal between the lens and the fixture housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy the hi-temp version\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAn incandescent lamp puts real heat into a sealed fixture. The special hi-temp compound is made to live with that without hardening and shrinking the way an ordinary gasket would, so it keeps its squeeze and keeps water out for longer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReplace it every time the light is opened\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA gasket that has been clamped and heat cycled takes a permanent set in the shape of its groove. Put it back and it may look fine, but it no longer has the spring to seal against a freshly torqued lens. Fitting a new gasket at every re lamp is the single cheapest way to avoid a flooded fixture.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48628943061204,"sku":"HAY-301-2086","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_54b5c91e-c9f5-4737-b1f5-52047d11fa23.jpg?v=1788758332","url":"https:\/\/www.activepoolsupply.com\/products\/lens-gasket-special-hi-temp","provider":"Active Pool Supply","version":"1.0","type":"link"}
