Flat “Half Gasket” for Sanke Keg to 2” Tri Clover Connection Food Grade Silicone This “Half Gasket” is different from a standard “Full Gasket” (SKU# 1059) in the following way: A “Full Gasket” has “ribs” that fit into the groove cut-outs of a Tri Clover connection. This groove will be on BOTH of the items you are connecting. A “Half Gasket” has only ONE “rib”. The other side is completely smooth and flat. WHY IS THIS IMPORTANT? Although a Sanke Keg can be connected to distilling columns, etc. using 2 inch Tri Clover fittings, the keg neck DOES NOT have a groove cut into it. More importantly: Due to the thickness of the flange in the Sanke keg’s neck it is very difficult to get a Tri-Clover clamp to fit around the neck, the “Full Gasket”, and the flange of the column. Even if you DO somehow manage to squish the connection together there is a strong likelihood of leaks, and of eventual failure of the gasket. Enter the NorCal Brewing Solutions “Half Gasket” to save us all! CHARACTERISTICS and SPECIFICATIONS: 2” Tri Clover compatible groove on one side, completely flat on the other Works with any size Sanke keg (American, European, 15.5 gallon, 50 Liter, 6 gallon, 5 gallon, and most others.)
