Waterway Plastics 400-1410B Eyeball Fitting - 3/8 inch Eyeball 1.5 inch MPT White

What This Part Is Used For
The Waterway Plastics 400-1410B eyeball fitting is a threaded return component used to direct water back into the pool. It features a 0.375 inch eyeball combined with a 1.5 inch male pipe thread base. This configuration allows direct threaded installation while delivering higher velocity return flow. It is commonly used in pool wall returns requiring precise flow control.

Why This Part Matters
Threaded return fittings must seal securely while maintaining directional control. A damaged or mismatched threaded eyeball fitting can leak or shift under pressure. The smaller eyeball opening increases return velocity, which can improve circulation in targeted areas. Using the correct threaded return fitting ensures stable performance.
