The Waterway 400-1421E 1 inch eyeball fitting is designed for compatible return and inlet applications using a 1-1/2 inch insider fit, a 2-3/8 inch face diameter, and a 1 inch orifice. Eyeball fittings are useful because they help direct returning water flow, which can influence circulation patterns and overall system performance.

The black finish gives this fitting a strong visual profile that can blend especially well with darker pool or spa interiors. Replacing a worn or mismatched eyeball fitting with the proper Waterway part can improve both directional control and the finished look of the return point.

For compatible inlet and outlet service work, this Waterway eyeball fitting is a practical replacement when controlled return direction and a darker visual finish are both desired.
