This is the tri-clamp vorlauf and sparge assembly that we use on the Ruby Pro series brewing systems. It can be adapted to any mash tun with a full diameter welded 1.5” TC fitting near the top. Please specify approximate length from outside edge of TC fitting to kettle center in comments when ordering. Feel free to call with any questions regarding fit, assembly or operation. Does not include clamp or gasket (those can be ordered separately). Please note that this version does not fit the Alpha Ruby and Fusion series brewing systems. We do offer a weldless version that will fit those systems available here
