It is approximately 30 inches in diameter and 3\/8 inch thick, and it may fit other filter models built on the same tank.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA side mount filter tank is made in two halves held together by a clamp band, and this ring is the seal on that split. It is the largest o-ring on the filter and the one that gets disturbed every time the tank is opened for a grid or media service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSeat the ring fully in its groove all the way around before the top half goes back on, and use a silicone based o-ring lubricant so it does not roll or pinch as the clamp is drawn up. Petroleum grease attacks the rubber and should not be used. A pinched tank ring will not seal at pressure no matter how tight the clamp is.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCross references\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe same ring appears under the numbers 152038, O-185, 4600-2038 and 90-423-1185, which is useful if you are matching against an old parts list.\u003c\/p\u003e","brand":"Aladdin","offers":[{"title":"Default Title","offer_id":48634846281940,"sku":"ALA-601-5526","price":16.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_3d7d70b0-17c5-4d87-a3e2-b1d6b939093e.jpg?v=1788837935","url":"https:\/\/www.activepoolsupply.com\/products\/tank-o-ring-pf50","provider":"Active Pool Supply","version":"1.0","type":"link"}
