It measures 5-3\/16 in across the outside, has a 3\/4 in center hole and is 1\/4 in thick.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it seals\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eInside a multiport valve, a rotating diverter presses down onto this gasket. The spokes of the gasket divide the valve body into separate ports, and every setting on the handle, filter, backwash, rinse, waste, works only because those ports stay isolated from one another. The gasket is the seal doing that job.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen it has failed\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eRubber hardens, takes a set, or tears at a spoke. Once it does, water crosses between ports inside the valve, and the visible symptoms follow: sand or DE returning to the pool, water running to waste while the valve is set to filter, or pressure that will not build. Replacing the spider gasket is the first repair to try in all of those cases.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eConfirm the fit\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe source lists this gasket for a 1-1\/2 in multiport valve and also files it with six position top mount valve parts covering models 501131, 501130 and 501231. The three dimensions above are the reliable check, so measure the old gasket before ordering.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48626384142548,"sku":"PAC-061-7497","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_e4bf2957-b0ac-4db5-a8f4-418c6c7573dc.png?v=1788709574","url":"https:\/\/www.activepoolsupply.com\/products\/valve-gasket-5-3-16-od","provider":"Active Pool Supply","version":"1.0","type":"link"}
