What this part does A keg coupler connects your keg, gas supply, and beer line so draft beer can flow. It lets pressurized CO2 or nitrogen enter the keg through the side air inlet and allows beer to exit through the beer line toward your faucet. Without a proper coupler, a draft system cannot dispense beer reliably. Why you need it Ensures a secure, leak connection between keg valve, gas line, and beer line for consistent pours. Controls gas delivery into the keg so pressuredriven dispensing works as intended. Made of beersafe materials to preserve flavor and avoid metallic offtastes. Key features and materials Body: nickelplated brass for strength and corrosion resistance. Probe and all beercontact components: 304 stainless steel to ensure sanitary contact with beverage and longlasting performance. Designed to accept the gas line on the side hose nipple and the beer line on the , connecting directly to the keg valve. Performance benefits Durable construction withstands regular use in home or commercial draft systems. Stainlesssteel wetted surfaces minimize flavor contamination and maintain beer quality. Simple, reliable operation ensures steady, quality pours when properly installed. Easy installation and use Attach the coupler to the keg valve, connect the gas line to the side nipple, and attach the beer line to the outlet. When engaged and pressurized, the coupler allows gas to push beer up the beer line and out the faucet. Compatible with systems using either CO2 or nitrogen as the dispensing gas. Practical applications Home kegerator or garage tap: reliable connection for serving draft beer at gatherings or daily use. Bar, restaurant, or taproom: durable coupler for frequent service and consistent beverage quality. Events and catering: quick hookup for temporary draft setups serving beer, wine, soda, or other carbonated beverages. What it solves Prevents failed pours caused by improper or worn couplers. Avoids offflavors from nonfoodgrade contact materials. Provides a straightforward way to transfer regulated gas into the keg and dispense beverage under pressure. Notes: installs between the keg valve, the regulator's gas line, and the beer line; uses pressurized CO2 or nitrogen depending on the beverage being dispensed.
