Viton and carbon hold up to both, so the seal keeps its face and its elasticity in water that would age a standard AS-1000 or PS-1000 seal early. The dimensions are unchanged, so it drops into the same 5\/8 inch shaft position.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat failure looks like\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA worn shaft seal leaks between the motor and the seal plate. Left alone, that water tracks down the shaft and into the motor. If the motor has started to scream, water has probably already been inside it, and the motor is likely due for replacement along with the seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstalling it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe seal arrives in two pieces: the ceramic seat with its rubber back, and the carbon face with spring and cup. A thin film of silicone on the back of the stainless cup keeps water from weeping past where it meets the plastic seal plate. Keep silicone off the seal face itself, and press the seat until it bottoms out. Always fit a new seal when you take a pump apart.\u003c\/p\u003e","brand":"US Seal","offers":[{"title":"Default Title","offer_id":48627690438868,"sku":"USS-60-5010","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_6f90e8f8-fc58-4e60-9cfe-1c4c496cc797.jpg?v=1788726663","url":"https:\/\/www.activepoolsupply.com\/products\/heavy-duty-salt-and-ozone-service-shaft-seal-viton-carbon","provider":"Active Pool Supply","version":"1.0","type":"link"}
