Waterway Plastics 400-1417B Eyeball Fitting - 3/8 inch Eyeball

What This Part Is Used For
The Waterway Plastics 400-1417B eyeball fitting is used in pool return systems to create a higher velocity return stream. The 0.375 inch eyeball opening restricts flow to increase directional force. This fitting is often used where stronger circulation or targeted jetting is needed. It is commonly installed in wall return housings.

Why This Part Matters
Smaller eyeball openings increase return velocity, which can improve circulation in problem areas. Using the wrong eyeball size can result in weak flow or excessive turbulence. This size is selected when focused water movement is required. Proper eyeball selection helps fine-tune system performance.
