Aquamoto White 3/8" Directional Flow Eyeball Inlet Jet, 1-1/2" Thread, 6 Pack with Installation Tool, 25552-100-000

These are Aquamoto white directional flow eyeball inlet jets with a 3/8 inch orifice and a standard 1-1/2 inch thread, sold six to a pack with an installation tool.

What the eyeball does

The eyeball is the swivelling insert in the return fitting. Because it pivots, the return flow can be aimed. That is what turns a pool over properly instead of leaving still corners where debris settles and chemicals never really arrive.

The 3/8 inch orifice

A narrower orifice pushes the same flow through a smaller opening, so the water leaves the return faster and reaches further across the pool. This pack uses the 3/8 inch size.

Sold as a set

Six fittings arrive together with the installation tool, which is the sensible way to buy them: returns tend to age at the same rate, and doing all of them at once costs little more than doing one.
