This is a weldless version of the vorlauf and sparge assembly that we use on the Ruby Pro series brewing systems. It can be adapted to any mash tun with a 13/!6” diameter hole near the top. Please specify approximate length from outside edge of TC fitting to kettle center in comments when ordering for a custom application. 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 fit Alpha Ruby and Fusion series brewing systems.
