Description
When your spray pattern isn’t quite right or you need to dial in a different flow rate, the problem might be a worn orifice or simply the wrong size for your application. This #18 stainless steel orifice plate gives you precise control over your spray output and keeps your system running efficiently, whether you’re spraying herbicide, fungicide, or liquid fertilizer.
What You’re Getting
- Precision-machined stainless steel construction that won’t corrode or wear out from chemical exposure
- Size #18 orifice provides consistent, repeatable flow rates for accurate application
- Direct replacement part that fits standard TeeJet cap assemblies
- Professional-grade quality that maintains its dimensions season after season
Built for Real Farm Work
This orifice plate works with TeeJet spray systems commonly found on boom sprayers, spot sprayers, and air blast equipment. The #18 size is perfect for medium flow applications where you need reliable coverage without overdoing it. Whether you’re running a broadcast sprayer across corn and bean fields or using a three-point sprayer for pasture work, this orifice delivers the flow control you need.
Made to Last
Stainless steel construction protects the orifice from clogging and damage caused by abrasive chemicals and field debris. Unlike brass or plastic alternatives, stainless steel maintains its precise dimensions even after thousands of acres and exposure to the toughest farm chemicals. The orifice keeps its shape so your spray pattern stays consistent from spring through fall.
Installation Notes
This orifice plate installs inside your existing TeeJet cap assembly—just remove the old plate and drop in the new one. If your spray pattern starts getting uneven, it’s usually time to clean debris out of the orifice before replacing it. Keep a spare on hand since switching between different orifice sizes lets you adjust flow rates without changing your entire spray tip setup.
