Keg Coupler FAQ
How do I know which coupler system my keg needs?
Match it to the keg's country of origin and brand: US domestic beers use D-system (Sankey), most European lagers use S-system, German/Irish/specialty kegs use A, G, M, or U systems, and one-way bag kegs use KeyKeg couplers. When in doubt, tell us the brand and we'll confirm before you order.
What happens if I order the wrong coupler?
It simply won't lock onto the keg valve — couplers are system-specific and there's no universal fit. It's the most common wrong-item order in draft equipment, which is exactly why confirming the system before ordering is worth the extra minute.
