This sprayer is most commonly used to aerate wort while transfering to the primary fermenter. Simply place this on the end of the siphon or transfer hose. When the wort hits the end it will spray out.
The siphon sprayer can also be used for sparging on all-grain systems. Spraying the water over the grains will help prevent tunneling in your mash tun.
Fits 3/8" hose.
