A cracked, warped, or broken diffuser concentrates flow in one area of the sand bed — bypassing clean sand, reducing filtration effectiveness, and causing channeling. Replacing it with the correct OEM part restores balanced, full-bed water distribution.\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;\"\u003e154906\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #ffffff;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePart Name\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eDiffuser Assembly\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\u003eFits Filter Model\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eTR140\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #ffffff;\"\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;\"\u003eEach (1)\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eFits Into\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\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eEquipment Line\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eModel \/ Part Number\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #ffffff;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003ePentair\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eTriton II\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eTR140\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eDiffuser assembly for TR140\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cem\u003eCompatibility is based on Pentair parts documentation and available OEM records.

Debris around the standpipe O-ring or a damaged lateral can replicate the same poor-filtration symptoms as a failed diffuser — addressing everything in one service visit saves you from opening the tank again. Confirm the correct sand load per your TR140 manual before closing up.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-30 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":51774195007763,"sku":"154906","price":63.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/PEN154906_0.jpg?v=1747703746","url":"https:\/\/poolaroo.com\/products\/pentair-tr140-diffuser-154906","provider":"Poolaroo","version":"1.0","type":"link"}
