It is molded in plastic, the same as the original.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy the diffuser matters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe diffuser wraps the impeller and turns the speed of the water leaving the vanes into usable pressure. A cracked or distorted diffuser lets water recirculate instead of moving forward, so the pump sounds normal but the filter gauge and the return flow both drop.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat to look for\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eCheck the face where the impeller runs for cracks, look at the mounting bosses for chips, and see whether the part still seats tightly. Any of those means the diffuser is done.\u003c\/p\u003e\u003cp\u003eIf you are already replacing the impeller or the shaft seal, do the diffuser at the same time. The pump is apart, the parts wear together, and a new impeller in a worn diffuser will not give you the flow you paid for.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48627359154388,"sku":"HAY-101-2059","price":51.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_9c0467dd-9cf9-42d3-8d18-44ee89dc08ea.png?v=1788722827","url":"https:\/\/www.activepoolsupply.com\/products\/diffuser-5hp-1-5hp-fr-75hp-2hp-ur","provider":"Active Pool Supply","version":"1.0","type":"link"}
