{"product_id":"gasket-for-sand-filter","title":"Waterway Gasket for Sand Filter","description":"\u003cp\u003eThis is the Waterway 711-1920 gasket for the sand filter valve joint on the older Clearwater sand filter. It is a clear white round gasket with ridges across the face and a slight lip at the inside edge.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich valve it suits\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt belongs on filters fitted with the clamp style valve, where a band clamps the valve down to the tank. The later split nut style valve does not use this gasket at all, it seals with an o-ring, so identify the valve on your filter before ordering. A quick look at the joint answers it: a band clamp means this gasket, a large threaded nut means the o-ring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe gasket measures 7-1\/8 inches across the outside and 5-5\/8 inches across the inside. Thickness is about 1\/8 inch at the outer edge and 1\/4 inch at the inside lip. Note the way the old gasket sat as you take it out so the lip goes back the same way.\u003c\/p\u003e","brand":"Waterway","offers":[{"title":"Default Title","offer_id":48634023379156,"sku":"WWP-851-1920","price":17.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_517afa1c-8c3e-4305-81da-a05721c68132.png?v=1788824887","url":"https:\/\/www.activepoolsupply.com\/products\/gasket-for-sand-filter","provider":"Active Pool Supply","version":"1.0","type":"link"}
