"S" system, also known as European Sankey, is used by many European breweries such as Heineken, Beck's, Amstel Light and Pilsner Urquell. It has a longer, narrower probe than the D system. The KT86S-L keg coupler features a stainless steel body and probe that are resistant to chemicals and won't chip like chrome. The coupler has a lever handle with a stainless steel handle fork for added durability. The short handle is ideal for smaller diameter kegs.
