{"product_id":"strainer-cover-t-ring","title":"Hayward Strainer Cover T-Ring","description":"\u003cp\u003eThe Hayward SPX4000TS is the strainer cover T-ring for NorthStar pumps built between 1998 and 2007. It is the genuine Hayward part, molded in rubber, and it is also listed under the number O-510-0.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat a T-ring is\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt is the seal between the strainer cover and the pump body, and the T shaped profile is what makes it work. The ring sits in the groove and the flat of the T squares up as the lid comes down, so it holds a seal at low pressure and under vacuum. A round o-ring of the same diameter will not do the same job.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy they get replaced\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eLid seals harden, flatten and split with heat, sun and chemistry. Once that happens air finds its way in on the suction side, and the pump starts losing prime or running with a basket full of bubbles. Clean out the groove, fit the new ring, lubricate it and the problem usually goes with it.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48634522206420,"sku":"HAY-101-1516","price":49.15,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_bf0aa6a5-d76c-420b-8bc5-5f24b039bf45.gif?v=1788833753","url":"https:\/\/www.activepoolsupply.com\/products\/strainer-cover-t-ring","provider":"Active Pool Supply","version":"1.0","type":"link"}
