Poolaroo Pro Tip

Before reseating this O-ring, clean the groove thoroughly to remove any debris or old lubricant residue. Apply a thin, even coat of silicone-based lubricant — never petroleum-based products, which degrade rubber — to extend seal life and prevent pinching during reassembly. Browse Pool Plumbing Lubricants for a compatible option.
