Take Apart Adjustable Emitters can be adjusted from 0 – 2.2 gph by rotating handle. Water drips through a slot in the side of the emitter. Available with a barbed inlet or on a stake. They can be taken apart for easy cleaning.  Attaches to 1/4″ distribution drip tubing. To prevent dirt from entering drip emitter (barbed inlet version), 6″ support stake may be used to keep emitter and end of tubing up off the ground. Works well at low pressures.
