Where directionally-specific water saturation is needed. O-Jet sprayers are used for ground covers and areas that need full water coverage. A small deflection cap creates a specific fan spray pattern that thoroughly saturates the area at a lower pressure than conventional sprinklers. See charts below. Connect the O-Jet to the end of the 1/4 tubing held by our 15 irrigation stake, or at the end of a riser tube (see picture at right) installed on the Spike Stake. Sprayers on riser tubes may also be connected directly into .5 poly tubing with a 1/4 threaded barb.
