Over time, o-rings naturally degrade — becoming brittle or flattened — which can lead to leaks or loss of prime. This OEM replacement restores sealing integrity, providing a tight, water- and air-resistant fit. Designed to Pentair’s original dimensions, it installs easily in the lid groove for fast maintenance turnaround.\u003c\/p\u003e\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eApply a thin layer of silicone o-ring lubricant before installation to ease seating and reduce wear. Always reuse an o-ring when opening the lid — pairing this with a refreshed clamp ring (eg, SKU 357239Z) helps maintain a complete, robust seal.\u003c\/p\u003e\n\u003ch3\u003eInstallation Tips\u003c\/h3\u003e\n\u003cp\u003eAlways disconnect the pump from power before servicing. Clean the seating surfaces and grooves thoroughly of debris before placing the O-ring. Don’t distort or stretch the o-ring — place it evenly. Use a compatible lubricant if needed and ensure proper reassembly of the ID and clamp.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Cavanaugh Pool, Spa \u0026 Patio, Inc.","offers":[{"title":"Default Title","offer_id":62589908779379,"sku":"357255Z","price":7.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/2464\/4211\/files\/357255Z_083cd3bf-5b31-4352-8547-2b0519afb0ed.jpg?v=1772564343","url":"https:\/\/shop.cavanaughpool.com\/products\/supermax-pump-parts-and-accessories-pentair-superflo-vs-vst-lid-o-ring-357255z","provider":"Cavanaugh Pool, Spa \u0026 Patio, Inc.","version":"1.0","type":"link"}
