A cracked, worn, or damaged diffuser reduces flow performance and can cause the pump to lose prime — replacing it with the correct OEM part restores the pump to its designed operating condition.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n\u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePentair Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eC1-216P\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eHP Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e1\/2 HP Full-Rated \/ 3\/4 HP Up-Rated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eCompatible Equipment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eMax-E-Glas \/ Dura-Glas Series Inground Pool and Spa Pumps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eQuantity Included\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eWhen replacing the diffuser, inspect the impeller and shaft seal at the same time — these components wear together and are accessible once the pump is disassembled to this depth. Replacing worn components together avoids a repeat teardown shortly after. Verify your pump's HP rating and model designation against the part number stamped on the original diffuser before ordering.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-14 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":51774181409043,"sku":"C1-216P","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/PENC1216P_0.jpg?v=1747702774","url":"https:\/\/poolaroo.com\/products\/pentair-1-2-hp-full-rated-3-4-hp-up-rated-diffuser-c1-216p","provider":"Poolaroo","version":"1.0","type":"link"}
