Buyer’s Guide: What to Consider
Choosing the right keg coupler depends on your keg type and setup. Here are key factors to consider before buying.
- Keg System Compatibility: Identify your keg type: D for American domestic, S for European, U for Guinness, A for German. Using the wrong coupler won't fit or may leak.
- Material Quality: Look for stainless steel probes and brass bodies for durability and sanitation. Avoid plastic parts that can crack or affect beer taste.
- Pressure Relief Valve: A relief valve lets you vent excess pressure safely, reducing foam and spills. Essential for home use to avoid messy taps.
- Space and Design: Low-profile couplers save vertical space, ideal for under-counter kegerators. Consider side connections if clearance is tight.
- Ease of Use: Lever handles are easier to operate than twist types. Look for ergonomic designs that make tapping and releasing simple.
