Replace the o-rings on your SS Brewtech Chronical or Unitank racking arm! This is a set of 4 o-rings that measure 10mm x 1.2mm. These are the o-rings that you need for the racking arm on the SS Brewtech Chronical Fermenter (Regular or Brewmaster Edition) or Unitank. It's always good to have a set of these on hand in case yours go missing or get damaged!
