It measures 6 inches on the outside and 1 inch on the inside, and it is the pattern used on valves built after 1976.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCount the spokes before you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAmerican Products used more than one spider gasket pattern over the years, and they are not interchangeable. Take the old one out and count the spokes. Five spokes means this part. Check the outside diameter too, since 6 inches is what confirms it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy they fail\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe spider gasket is what keeps each port of a multiport valve separate from its neighbors. As the rubber compresses and hardens, water starts crossing between ports inside the valve. The classic symptoms are a trickle out of the waste line while the valve is set to filter, or a backwash that never seems to finish clearing. Both are the gasket, not the filter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eClean the gasket channel in the valve body out completely before seating the new gasket, and press it in evenly all the way around. A silicone sealant or lubricant helps it bed in and stay put while the valve goes back together.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48626567577812,"sku":"AMP-061-1076","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_c1d4aa30-c3d8-4da6-b777-fbed529f397c.gif?v=1788712531","url":"https:\/\/www.activepoolsupply.com\/products\/5-spoke-spider-gasket-6-od","provider":"Active Pool Supply","version":"1.0","type":"link"}
