Super-Pro Venturi Tee Nozzle with 1/2 Inch Opening, 23306-120-020

The Super-Pro 23306-120-020 is a replacement venturi tee nozzle with a 1/2 inch opening. It is the insert that sets the jet size inside the tee.

What the opening does

A venturi works by forcing flow through a restriction so it speeds up. The nozzle is that restriction. Its opening is not a loose detail, it is the number that decides how the assembly behaves, which is why the same nozzle body is sold in more than one size.

When to replace it

Nozzles wear. Water carrying fine grit slowly opens the orifice, and once it has grown past its original size the jet slows and the venturi loses its bite. A fresh nozzle restores the original flow without touching the plumbing around it. Order by part number so you get the 1/2 inch opening rather than a similar looking nozzle in another size.
