Description

The CMP 25591-130-000 is the SpaMaster 2 inch double double roto internal jet, listed in white with stainless steel. It is the internal only, the part that drops into a jet body already set in the wall.

What roto means

A roto internal spins as water flows through it, so the stream sweeps around rather than pounding one spot. Double roto multiplies that action. It is the difference between a jet that feels like a jet of water and one that feels like a massage.

Why internals get replaced

The spinning surface is a wear point. Scale, grit and time eventually stop the nozzle turning, and once a roto jet stops rotating it is just a directional jet. Replacing the internal restores the action without touching the plumbing, since the body stays in the wall.
