MoreBeer!'s Patent Pending sparge arm design is the perfect addition to almost any all grain setup! This sparge arm assembly is made completely of stainless steel and silicone, and has two adjustment points. One of these will help to hold the sparge arm against your kettle, while the other allows you to move the sparge arm up or down inside the kettle to accommodate different amounts of grain. These adjustment knobs are very easy to hand tighten and loosen, meaning no tools are necessary. Excellent for sparging as well as recirculating your mash in a RIMS or HERMS system!,,To use, simply install on your kettle wall, tighten down the red stopper to hold the sparge arm in place, adjust the height of the bottom disc to be right above your grain bed but below the mash tun's water level, and adjust the flow level using the included ball valve. This unit will not include a barb or quick disconnect on the inlet of the ball valve, as every brewery is different. Please choose an inlet attachment from the sparge arms recommended items. Note - This sparge arm will not fit on most coolers.
