Tap a keg of your most popular brew with this coupler! Distinguished by its longer,Website:://.beerbreweryequipment.net, narrower probe, this coupler is compatible with "S" system keg valves, also known as European Sankey, which are used by many European breweries. Used by breweries like Heineken, Becks, Amstel Light, and Pilsner Urquell, this unit's compatibility is rivaled only by its durability. It boasts a forged brass body that's sure to last over the long haul and includes a chrome-plated probe that can be used for almost any beer except IPAs. For added safety and peace of mind, this model has an integrated pressure relief valve that stops the gas flow if pressure gets too high (at 55-65 PSI), while the 7/8"-14 beer port thread matches the United States beer industry standard for maximum compatibility.
