It is the genuine Sta-Rite part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it sits\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe seal plate carries the shaft seal and bolts up against the pump body. This o-ring is the joint between the two. It is out of sight and out of mind until the pump starts weeping from the middle of the wet end, at which point it is usually either this o-ring or the shaft seal behind it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eChange it with the seal\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eOnce the seal plate has come off, put a new o-ring back. A ring that has spent years compressed in a groove has taken a permanent set and will not seal the same way twice. Give it a coat of silicone o-ring lubricant so it seats evenly rather than rolling or pinching as the pump is drawn back together.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eModel coverage\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe listing names the Pinnacle. The same part is filed in the Sta-Rite parts diagrams for the Max-E-Pro, the Max-E-Glas and Dura-Glas, the Max-E-Glas II and Dura-Glas II and the IntelliPro VS, so confirm against your own diagram before ordering for one of those pumps.\u003c\/p\u003e","brand":"Sta-Rite","offers":[{"title":"Default Title","offer_id":48634963460308,"sku":"STA-101-3745","price":17.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_38c7f58b-7303-4824-b3ea-85b0e7743860.gif?v=1788839072","url":"https:\/\/www.activepoolsupply.com\/products\/seal-plate-o-ring-2","provider":"Active Pool Supply","version":"1.0","type":"link"}
