It is a size 2-336 ring, supplied as the genuine Pentair part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it goes\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe ring seals the diffuser inside the pump. It has to come off any time the pump is opened, which usually means an impeller change, a shaft seal job or a strip down after the pump has run dry. Rubber that has been heat cycled for years hardens and takes a permanent set, and once that happens it no longer seals against the mating face, so water bypasses the diffuser instead of being pushed through it.\u003c\/p\u003e\u003cp\u003eIt is a low cost part in the middle of a job that is not worth doing twice, so it is normally replaced on sight rather than inspected. The seal plate o-ring on these pumps is a separate Pentair part and is worth ordering at the same time.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48625849729236,"sku":"STA-101-2771","price":7.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_97686da1-3ac2-4635-b489-faf164e57b74.jpg?v=1788701621","url":"https:\/\/www.activepoolsupply.com\/products\/whisperflo-xf-diffuser-oring","provider":"Active Pool Supply","version":"1.0","type":"link"}
