Description

When your spray nozzle isn’t sealing properly or you’re getting pressure drops across your boom, it’s often the stem inside the cap that’s the culprit. This little part might not look like much, but it’s what keeps your chemical where it belongs—coming out the tip in an even pattern, not leaking around the threads or creating pressure inconsistencies down the line.

What You’re Getting

Precision-machined stem designed for TeeJet CP series nozzle caps
Creates tight seal between cap and nozzle body to prevent leaks
Maintains proper pressure flow for consistent spray patterns
Direct replacement part that installs without modifications

Built for Real Farm Work

This stem works with TeeJet’s CP series caps, which you’ll find on boom sprayers, three-point sprayers, and pull-type applicators across all kinds of farm operations. Whether you’re applying herbicides on corn and beans, spreading liquid fertilizer, or spot-spraying fence rows, having properly sealing nozzles makes all the difference in getting even coverage.

Made to Last

TeeJet builds these stems to handle the constant pressure cycling and chemical exposure that comes with spray applications. The materials resist swelling from solvents and won’t degrade when exposed to the wide range of farm chemicals you might run through your system over the years.

Installation Notes

The stem fits inside the nozzle cap and creates the seal against the nozzle body. If you’re replacing it, take a look at the cap threads and body seat while you’ve got things apart—sometimes a quick cleanup with a wire brush helps ensure a proper seal. Keep the old stem as a spare since they’re small and easy to lose in the field.
