Description

When your orchard or vineyard sprayer starts putting out an uneven spray pattern or doesn’t have the volume it used to, chances are good the core orifice needs replacing. This brass core is the heart of your disc-core nozzle system—the precision-machined part that controls flow rate and creates the right droplet size for getting chemicals into the canopy where they need to be.

What You’re Getting

Precision brass construction that won’t wear down from chemical exposure like plastic cores do
Size #35 orifice designed for medium flow applications and consistent spray patterns
Drop-in replacement for worn cores—no modifications needed
Built to TeeJet’s original specifications for reliable performance season after season

Built for Real Farm Work

This core is designed specifically for air blast spraying systems—the type you’ll find on orchard sprayers, vineyard equipment, and specialty crop applicators. These systems use air to carry fine droplets into crop canopies for thorough coverage when applying insecticides, fungicides, and other crop protection products. The #35 size gives you the flow rate needed for medium-sized operations without wasting product.

Made to Last

Brass holds up to farm chemicals and daily use better than plastic alternatives, keeping the orifice shape precise and threads sharp. This is the same quality material TeeJet has been using for decades in agricultural spray systems. You won’t find yourself constantly replacing worn cores when you go with brass construction.

Installation Notes

The core drops right into your existing disc-core nozzle body—typically takes just a minute to swap out. 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 spare on hand during busy spraying seasons, and always inspect cores before putting the sprayer away for winter storage.
