It is the genuine Pentair part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it seals\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe bottom of a Rainbow feeder is under constant pressure and constant chemical exposure, and the o-ring at that joint is what keeps the water inside. Over a few seasons it hardens, takes a set, and eventually weeps. A slow drip at the base of the feeder almost always traces back to this ring rather than to the body or the fittings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting notes\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the new style ring. On an older feeder, compare it against the seal you remove before you reassemble. A thin film of o-ring lubricant on the new ring helps it seat and slows the hardening, and it is worth replacing the ring any time the feeder is opened for other service.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48625741889748,"sku":"RAI-451-4212","price":2.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_3c7e526d-6144-47f3-92ae-3a6bbfb4f8d2.jpg?v=1788690459","url":"https:\/\/www.activepoolsupply.com\/products\/bottom-o-ring-new-style","provider":"Active Pool Supply","version":"1.0","type":"link"}
