Before fitting the new O-ring, clean the groove in the strainer pot cover to remove any grit or old lubricant residue, then apply a thin, even coat of silicone-based lubricant. Browse \u003ca href=\"https:\/\/poolaroo.com\/collections\/pool-plumbing-lubricants\"\u003ePool Plumbing Lubricants\u003c\/a\u003e for a compatible option. Never use petroleum-based products — they degrade rubber O-rings rapidly. Tighten the strainer cover by hand only; over-tightening can distort the O-ring and cause the very leak you are trying to fix.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-18 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":54303487066387,"sku":"SPX4000S","price":53.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/HPPSPX4000S_0.jpg?v=1781650677","url":"https:\/\/poolaroo.com\/products\/hayward_spx4000s","provider":"Poolaroo","version":"1.0","type":"link"}
