Waterway Plastics 2-Inch Heater O-Ring/Gasket (Pack of 4)

Keep your Waterway heater connections sealed with a ready-to-use pack of four Waterway Plastics grooved O-ring/gaskets. These pieces are sized for a 2-inch heater inlet and are designed to deliver a reliable fit when replacement is needed. Each gasket measures about 2 1/8 inches inside diameter and 2 15/16 inches outside diameter, offering a consistent footprint that aligns with standard Waterway components. This set is ideal for maintenance days, spill-abatement checks, or routine equipment refreshes, helping you stay prepared without waiting for single-part delivery.

What you receive is a genuine Waterway replacement set built to match the 711-4030 grooved gasket profile. The grooved design supports a more uniform seating surface, which can contribute to a steady seal during operation. While real-world results depend on the surrounding plumbing and system conditions, having a four-piece pack on hand can reduce downtime and simplify planning for scheduled service windows.
