Description
When you’re spraying orchards, vineyards, or specialty crops with your air blast system, having the right orifice size makes all the difference between good coverage and wasted chemicals. This #56 brass disc core gives you precise flow control for those bigger applications where you need more volume without sacrificing pattern quality.
What You’re Getting
- Machined brass construction that holds its shape through thousands of spray cycles
- Size #56 orifice delivers higher flow rates perfect for dense canopy work
- Core design works seamlessly with air blast systems to create consistent droplet patterns
- Direct replacement that fits standard TeeJet disc-core cap assemblies
Built for Real Farm Work
This core is designed specifically for air blast sprayers—the workhorses you’ll find in orchards, vineyards, and specialty crop operations. Whether you’re applying fungicides to apple trees, treating grape vines, or handling nut crops, this larger orifice size handles the volume you need for thorough coverage on bigger jobs.
Made to Last
Brass holds up to farm chemicals and daily use better than plastic alternatives. The threads stay sharp, the orifice keeps its shape, and you won’t find yourself constantly replacing worn-out tips. This is the same quality material TeeJet has been using for decades in agricultural spray systems.
Installation Notes
This disc core threads directly into your existing TeeJet cap assembly—no modifications needed. 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 tip. Keep a spare on hand since switching between different flow rates is as simple as swapping cores.
