{"product_id":"eq-series-diffuser-o-ring","title":"Pentair EQ Series Diffuser O-Ring","description":"\u003cp\u003eThe Pentair 350037 is the diffuser o-ring for EQ Series commercial pool pumps. It is a new genuine Pentair part, and the listing notes it may also fit other Pentair pool pumps.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it seals\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe diffuser sits over the impeller and converts its velocity into pressure. This o-ring seals the diffuser against the housing, and without a good seal a share of that pressurized water simply circulates back to the suction side instead of going out to the pool. On a commercial pump that shows up as lost flow and a motor working harder than it should.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eRubber takes a set. Any o-ring that has been clamped and heat cycled for a few seasons will be flat and hard, and it will not reseal properly once it has been disturbed. Replace it whenever the pump is opened for a shaft seal, an impeller or a diffuser, and check the old ring against this one before fitting if your pump is outside the EQ range.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48626570199252,"sku":"PAC-101-6506","price":26.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_ab7ed0e5-487c-480c-a5b9-aa8876731872.jpg?v=1788712572","url":"https:\/\/www.activepoolsupply.com\/products\/eq-series-diffuser-o-ring","provider":"Active Pool Supply","version":"1.0","type":"link"}
