Now with a piston pump, operated by a maximum-leverage pump handle, which can be mounted on either side of the tank. Pump chamber holds pressure, so minimum pumping effort will produce consistent pressure (maximum pressure is 90 psi) for a wide range of spraying tasks.

  • High-impact, UV resistant polyethylene tank is made for hard field use.
  • Leakproof lid has a one-way valve that lets air enter the tank (to prevent vacuum build-up) but keeps the spray material in.
  • Large filler port with its removable strainer, permits quick on-site refills without a funnel. Dirt and large particles are further screened by the built-in filter in the piston chamber.
  • 22" spray wand is reinforced with fiberglass and comes with a trigger sprayer, quality shut-off valve, and 4 nozzle options (fan, hollow cone, plastic adjustable and jet stream spray patterns).

We especially recommend the brass adjustable spray nozzle.
