How to pick the right spray nozzle
Every broadcast sprayer tip has to do two jobs at once: put out the right amount of liquid, and break it into droplets the right size for what you're spraying. The selector above solves both. It works out the flow each tip needs from your target rate, ground speed and tip spacing, then filters TeeJet's tip lines by the droplet size your application calls for, and shows you only the sizes we have on the shelf in Spokane.
Step 1: Flow per nozzle (GPM)
The flow a single nozzle has to deliver is set by three numbers you already know — gallons per acre, miles per hour, and inches between tips on the boom:
For example, 15 GPA at 12 mph on 20-inch spacing needs 0.61 GPM per tip. That is the number you match against a TeeJet nozzle chart. A tip's size code is its flow at 40 psi (an 04 tip = 0.4 GPM at 40 psi), and flow rises with the square root of pressure, so an 04 tip can cover roughly 0.28–0.6 GPM across its rated pressure range. Running near the middle of that range gives the best pattern.
Step 2: Droplet size for the job
The same 0.4 GPM can come out as a fine mist or a coarse stream depending on the tip design. That is why the selector asks what you are applying:
- Contact herbicides, fungicides and insecticides need coverage, so fine-to-medium droplets from an XR, DG or Turbo TeeJet (TT) tip usually win. TwinJet tips (TTJ60, DGTJ60) split the fan front and back for better canopy penetration in dense crops.
- Systemic herbicides like glyphosate translocate through the plant, so you can trade coverage for drift control with medium-to-coarse droplets from a TT, AIXR or TTI tip.
- Soil-applied products don't need fine droplets at all — very coarse from an AIXR or TTI keeps the product on target.
- Dicamba and 2,4-D choline labels (XtendiMax, Engenia, Enlist One/Duo and similar) mandate a specific ASABE droplet category, usually very coarse or ultra coarse, and often list approved nozzles by name. TTI is the usual answer; always check the label.
Sizing fertilizer orifice plates for UAN and 10-34-0
Liquid fertilizer runs through a stainless CP4916 orifice plate instead of a spray tip, and the chart on the package is for water. 28% UAN weighs 10.65 lb/gal, 32% weighs 11.06, and 10-34-0 weighs 11.65 — heavier liquid flows slower through the same hole. The selector's Fertilizer Orifice Plates mode applies the specific-gravity correction (√(lb/gal ÷ 8.34)) automatically, converts your row spacing and nozzles-per-row into an effective spacing, and picks plates that land in the middle of the 5–60 psi chart rather than at the edges where flow is hard to control. It also tells you which tip strainer mesh to run so the plate doesn't plug. Go straight to the fertilizer orifice calculator →
If your rate controller has to hold a rate across a wide speed range — corn sidedress, for instance — a TeeJet SJ7A-VR or SJ3-VR variable-rate StreamJet cap covers 2–3× the flow of a fixed plate in one part. The selector shows the speed window each VR size covers at your rate.
Liquid deicer and anti-icing nozzles
Salt brine, magnesium chloride and calcium chloride are applied with TeeJet SJ3 StreamJet tips, which lay the liquid down in three solid streams instead of a fan so nothing drifts and the striped pattern leaves traction between the stripes. Road crews size in gallons per lane-mile; parking lots and walkways in gallons per 1,000 square feet. The Liquid Deicer mode takes either unit plus your lane width, speed and brine type (23% salt brine, 30% mag chloride, 32% calcium chloride or potassium acetate), and returns the SJ3 size, the pressure to run and the color-matched cap. Pre-season is the time to check this — calibrate with a catch test before the first storm. Go straight to the deicer nozzle selector →
Common questions
What size nozzle do I need for 15 GPA?
It depends on speed and spacing. At 10 mph on 20-inch centers, 15 GPA needs about 0.5 GPM per tip — an 05 tip at 40 psi. At 14 mph it climbs to 0.71 GPM, so you'd move to an 06 at 55 psi or an 08 at a lower pressure. Type your numbers into the selector above and it will do the math against our stock.
What's the difference between XR, AIXR, TT and TTI TeeJet tips?
XR is the standard flat fan — best coverage, most drift. TT (Turbo TeeJet) is a wide-angle tip that runs one droplet category coarser. AIXR adds air induction for large, air-filled droplets with real drift control. TTI is TeeJet's most drift-resistant broadcast tip and the go-to for very coarse label requirements.
Can I use a spray tip chart for liquid fertilizer?
Only after correcting for weight. 28% UAN is 28% heavier than water, so a plate flows about 12% less UAN than the water chart says. The selector applies that correction for you.
What pressure should I run my sprayer at?
Most flat-fan tips are rated from 15 to 60 psi (TT, AIXR and TTI to 90), and each one's pattern is best in the middle of its range — roughly 30–50 psi. If the selector shows a tip needing pressure near the edge of its range, the next size up or down will give you more room to work with as speed changes.
