It is sold as a seal that fits a number of pool pumps rather than as a single model part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck it by measurement\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSeals are matched by dimension, not by pump name. This one takes a 3\/4 inch shaft, measures 1-9\/16 inch across the seal outside diameter, and its mating ring is 1-3\/8 inch in diameter by 13\/32 inch thick. Compare those against the seal you pull out and you will know whether it is the right part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe failure it fixes\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe shaft seal is what keeps pump water from following the shaft back into the motor. When it fails you get water weeping from between the seal plate and the motor, and left long enough that water finds the motor bearings. Replace the seal whenever the wet end is opened, since a seal that has been removed will not reseat properly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSalt and ozone pools\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAn extra heavy duty version of the same 3\/4 inch seal is stocked separately for saltwater and ozone systems, which are harder on seal materials.\u003c\/p\u003e","brand":"US Seal","offers":[{"title":"Default Title","offer_id":48633999360212,"sku":"USS-60-5019","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_03c74b60-7445-4e67-8d77-77c6cf03cfbd.jpg?v=1788823582","url":"https:\/\/www.activepoolsupply.com\/products\/shaft-seal-assembly-3-4-shaft","provider":"Active Pool Supply","version":"1.0","type":"link"}
