{"product_id":"eq-series-o-ring-seal-plate","title":"Pentair EQ Series Seal Plate O-Ring","description":"\u003cp\u003eThe Pentair 356780Z is the seal plate O-ring for the EQ Series commercial plastic pump. It measures 11 inches across the outer diameter with a 3\/8 inch thickness, and it is the genuine Pentair part rather than a generic ring cut to size.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it seals\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the large static seal between the pump housing and the seal plate. It carries no rotating load, but it holds back everything the pump moves, so when it hardens or takes a permanent set the pump starts weeping at the case seam and loses prime on start up. A ring that will not spring back when you press it is finished.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt suits the EQ-Series commercial plastic pump in both configurations, with the hair and lint strainer and without it. Because it is a wear item that is disturbed every time the pump is opened, most techs fit a fresh one whenever the seal plate comes off rather than reusing the old ring.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48626584158420,"sku":"PAC-101-6780","price":59.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_49df3105-f4cd-4dba-a58e-661fb05d3abc.png?v=1788712730","url":"https:\/\/www.activepoolsupply.com\/products\/eq-series-o-ring-seal-plate","provider":"Active Pool Supply","version":"1.0","type":"link"}
