Pressure couplers, distributors, and regulators are essential components for restaurants and bars that serve draft beer. These devices help to ensure that the beer flows smoothly from the keg to the tap, with the right amount of pressure and carbonation. Pressure couplers are used to connect the keg to the beer lines, while distributors help to control the flow of beer to multiple taps. Regulators, on the other hand, are responsible for maintaining a consistent pressure inside the keg, which is critical for preserving the flavor and quality of the beer. In short, pressure couplers, distributors, and regulators play a crucial role in delivering a high-quality draft beer experience for customers at any restaurant or bar.
