This 15" whirlpool works perfectly with the 6.5 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 15" Swirly fits any vessel that is 11"-21" in container height.
