Description

You know that feeling when your sprayer keeps dripping after you shut it off, or when the boom sections won’t hold pressure evenly? A worn check valve is usually the culprit. This TeeJet diaphragm check valve stops backflow and keeps your sections flowing consistently, so you can focus on getting your crops covered instead of fussing with equipment that won’t behave.

What You’re Getting

10 PSI activation pressure that keeps boom sections primed and ready
Nylon construction that resists chemical corrosion and won’t crack like cheap plastic
1/4 inch Male NPT connection that fits standard TeeJet QuickJet body systems
Diaphragm design that seals tight when pressure drops, preventing drip and backflow
Smooth internal flow path that won’t restrict your spray pattern or pressure

Built for Real Farm Work

This valve is designed to work in TeeJet sprayer boom systems where consistent pressure and flow control matter. Whether you’re running a 3-point hitch sprayer on the back forty or pulling a big field sprayer through corn, this check valve keeps each boom section working independently so you get even coverage across the whole width.

Made to Last

Farm chemicals are tough on equipment, but this nylon body holds up to the herbicides, fungicides, and fertilizers you’re putting through it. The internal diaphragm stays flexible season after season, and the whole assembly handles the vibration and temperature swings that come with field work.

Installation Notes

This drops right into your existing QuickJet body setup—no modifications needed. Make sure you install it with the flow arrow pointing in the right direction, and check that your boom sections hold pressure after installation. If you’ve got multiple sections, it’s worth replacing them all at the same time so they all crack at the same pressure.
