{"product_id":"lid-o-ring-eq-series","title":"Pentair Lid O-Ring EQ Series","description":"\u003cp\u003eThe Pentair 350166Z is the lid o-ring for EQ Series commercial pumps. It seals the lid on the hair and lint strainer pot. Pentair describes this part both as the lid o-ring and as the strainer lid gasket, so you may see it listed either way; the part number is the same.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe seal that keeps prime\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eEverything upstream of the impeller is under suction, which means a bad lid seal draws air rather than spilling water. That is why a leaking strainer lid rarely leaves a puddle and often shows up instead as air in the pot, a pump that loses prime, or falling flow. Replacing a hardened or flattened ring is usually the whole repair.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAny time the lid comes off for a basket clean is a good moment to look at the ring. If it has taken a permanent set, cracked or gone stiff, replace it rather than dressing it and hoping. If the part you actually need is the lock ring seal instead, that is a separate Pentair number for the EQ Series.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48627952287956,"sku":"PAC-101-6514","price":33.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_4f9b1587-9cbb-4efb-b349-4c11a5d39d36.jpg?v=1788730800","url":"https:\/\/www.activepoolsupply.com\/products\/lid-o-ring-eq-series","provider":"Active Pool Supply","version":"1.0","type":"link"}
