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 15"-27" in container height.
