The Sparging Spear is simple: it is six feet of stainless steel rod with 1/4" male NPT threads at each end. Attach one of our Sparging Stones at one end and your gas process fitting at the other. Place the stone in an open top fermenter for passive sparging.

To make it less expensive to ship we cut it in half. Simply thread the two three foot halves together. You can also use just one half for smaller tanks or bins.
