Description
When you’re running an air blast sprayer in the orchard or vineyard and need consistent spray patterns for crop protection, the orifice core is the heart of your nozzle system. This #13 brass orifice gives you the precise flow control you need to deliver insecticides and fungicides exactly where they belong. If your spray pattern is getting uneven or your coverage isn’t what it used to be, a worn orifice core is usually the culprit.
What You’re Getting
- Brass construction that holds up to farm chemicals and daily use better than plastic alternatives
- Precision-sized orifice that keeps its shape and maintains spray pattern consistency
- Size #13 orifice designed for medium flow applications on air blast systems
- Direct replacement core that works with your existing TeeJet nozzle body
Built for Air Blast Applications
This core is designed specifically for air blast sprayers—the workhorses you’ll find in orchards, vineyards, and specialty crop operations. The orifice works with air assist systems to break up the spray into fine droplets that get carried into the crop canopy. It’s ideal for applying insecticides, fungicides, and other crop protection products where complete coverage matters.
Made to Last
This is the same quality brass material TeeJet has been using for decades in agricultural spray systems. The brass construction resists chemical corrosion and wear that would quickly destroy plastic cores. You’ll get seasons of reliable performance before needing replacement, and the orifice will maintain its precise dimensions throughout its life.
Installation Notes
This core installs directly into your existing TeeJet nozzle body—no special tools required. A quick tip: if your spray pattern starts getting uneven, it’s usually time to clean debris out of the orifice rather than replace the whole core. Keep a few spare cores on hand during spray season so you can swap them out quickly if one gets damaged or plugged with debris.
