This sparge arm can be used on 5 and 10 gallon round coolers, keggles, and pots less then 18" wide. The black rubber rings adjust to fit the mash tun tightly. Also, the 3/8" stainless steel tub moves up and down to adjust to the level of the grain bed.
This sparge arm uses a siphon sprayer. Spraying the water over the grains will help prevent tunneling in your mash tun.
Dimensions: 18" wide, 9 " tall.
