It is a two piece assembly: a stationary ceramic seat pressed into the seal plate, and a rotating half that grips the shaft and spins against it. The two faces run against each other with a film of water between them, which is why a seal that has been run dry or run with sand in the water fails early.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to fit one\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWater dripping from between the seal plate and the motor is the classic failed seal. Fit a new one any time the wet end is opened up as well, because a seal that has been pulled off the shaft will not reseat properly. Match the shaft size, which for this part is 5\/8 inch.\u003c\/p\u003e","brand":"Aladdin","offers":[{"title":"Default Title","offer_id":48633998049492,"sku":"SPG-60-1001","price":15.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_a5d74ed5-da73-4a66-ad60-74f895f69989.jpg?v=1788823540","url":"https:\/\/www.activepoolsupply.com\/products\/shaft-seal-viton-heavy-duty","provider":"Active Pool Supply","version":"1.0","type":"link"}
