A quality service part is especially valuable when the rest of the equipment is still performing well. The S210S/S311SX/S220 Air Tube Screw is a Hayward replacement part used in sand filters & parts applications, with part number SX200Z2 for easier identification when matching existing equipment. Sand filter parts help distribute, drain, or control water through the filter tank, which is essential for reliable filtration and backwashing. It helps complete a proper hardware repair so surrounding parts can be tightened evenly and inspected more easily. It is well suited for seasonal service, rebuilds, and troubleshooting when one small component is causing the issue. For best results, clean the surrounding area before reassembly so the part seats cleanly and nearby components can be checked for wear.
