When you’re maintaining your sprayer, there’s nothing more frustrating than loose connections that let chemicals leak or air get in. This TeeJet brass locknut keeps your spray components secure on the boom, ensuring your chemicals go where they’re supposed to and stay at the right pressure for even coverage.
What You’re Getting
- Solid brass construction that won’t corrode when exposed to chemicals and weather
- Standard 11/16″ TeeJet cap thread fits most TeeJet spray components
- Secure threading that stays tight through vibration and field conditions
- Precision machined threads for easy installation and removal
Built for Real Farm Work
This locknut works with TeeJet spray tips, caps, and other boom components that use the standard 11/16″ cap thread system. Whether you’re spraying herbicides on row crops, applying fungicides in the orchard, or spot-treating weeds along fence lines, this little part keeps everything locked down tight so your sprayer works like it should.
Made to Last
Brass holds up better than steel when it comes to chemical resistance and corrosion. This locknut is built to handle years of exposure to herbicides, fungicides, and fertilizers without breaking down or seizing up on the threads. The material stays workable even after seasons of use.
Good to Know
Hand-tighten these locknuts first, then use a wrench to snug them down – you don’t need to over-torque brass fittings. Keep a few spares in your toolbox since they’re small and easy to drop in tall crops. If you’re switching between different spray tips frequently, these threads will stay smooth and easy to work with.
