This 21" whirlpool works perfectly with the 10.5 Gallon Foundry, brew kettles, and any other brewing system. The rotating rubber piece allows it to secure to the side of any vessel, no matter the thickness. The Swirly™ uses a 1/2" Straight Pipe Thread for hose connections and includes a hose barb for connecting your water supply. Patent pending.
The 21" Swirly fits any vessel that is 12"-27" in container height. For smaller vessels, see the 15" Swirly.
