Apply a thin, even coat of a silicone-based lubricant — never petroleum-based grease — to ensure a proper seal without degrading the O-ring material. Browse \u003ca href=\"https:\/\/poolaroo.com\/collections\/pool-plumbing-lubricants\"\u003ePool Plumbing Lubricants\u003c\/a\u003e for a compatible option.
