Three Hydroseeding nozzles from which to choose: the Straight Stream ( plastic cone ) or Brass Flat Fan nozzles: 50 or 80 degrees.
The two brass models have 3/4" NPT male thread. The red straight stream nozzle has a female 1 1/2" NPT thread.
The straight stream hydroseeding nozzle is best for throwing the hydroseeding material as far as your pump can send it. The brass nozzles have a flat fan pattern and are great for applying the hydroseeding materials as you are walking around.
