Euro "S" Type Sankey Coupler
Euro "S" Type Sankey Coupler works with European "S" system keg valves. These couplers would be required for commercial beers like Heinekin, Amstel, Stella Artois, and many more.
Although this coupler looks very similar to an American D-Style Coupler, the probe extends further down. Be careful not to screw this in to an American Sankey Keg, as it will engage the ball before locking into place, causing beer to spray out of the keg spear.
