De-Fly

Recommended Buy List

These are the parts we use and recommend. They are not required. The controller will run any 12 volt pump and any nozzles you plumb to it. Build the walk-through the way that fits your place.

Nozzle bodies and caps

This set makes a three-nozzle string on 3/8 inch hose: two ends and one in the middle that the hose runs through. The check valve in the middle body stops drip when the pump shuts off. You still pick the spray tips that snap into the caps.

QtyPart numberWhat it is
2 TeeJet 19349-211-406-NYB 3/8" hose barb, one outlet, QJ200 single nozzle body. End of a hose run.
1 19350-212-406-NYB Diaphragm check valve nozzle body, 3/8" hose, two barbs. Hose in and hose out. Middle of the run.
3 TeeJet 25598-3-NYR Cap and gasket. One per body. Holds a standard TeeJet spray tip.

Any TeeJet tip that fits a QJ200 cap will work. Flat fan or hollow cone, your choice. Same for a different brand of body and cap, as long as the hose and the brackets fit.

Nozzle and sensor mounts

Printed mounts that hold the nozzle bodies above and the De-Fly photo eyes on whatever your walk-through is built from. Every nozzle mount has the same slot: the body slides in sideways and locks down with its own nut. Sensor mounts have a 3/4 inch hole for the photo eye instead. Printed in UV-stable ASA. Clamp hardware is not included; it is in the table below. Pictures are in the Mount Catalog.

A typical walk-through needs three nozzle mounts and two sensor mounts. Tell us what you are mounting to and we will pick the set. To size a pipe, wrap a tape around it: 5-1/8 inches around is 1-5/8 pipe, 5-1/2 is 1-3/4, 6-1/4 is 2 inch, 7-1/2 is 2-3/8, 9 is 2-7/8.
