It is the only thing holding pressure at that joint, so when it hardens, flattens or takes a set from years of chlorine and heat, water starts to weep out around the lid. Owners often blame a cracked body when a two dollar seal is the real cause.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you fit it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe manufacturer information for this part is not consistent about the size designation. The product name calls it #2-151 and the description calls it #2-152, though both refer to Pentair part number 51016200. Compare the new ring against the old one before assembly, and lubricate it lightly with a silicone pool lubricant so it seats without pinching.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48628746518740,"sku":"AMP-061-1122","price":2.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/pentair_51016200.jpg?v=1788749647","url":"https:\/\/www.activepoolsupply.com\/products\/o-ring-2-151-diverter-valve","provider":"Active Pool Supply","version":"1.0","type":"link"}
