S-System FAQ
Does Guinness use an S-system coupler?
No — Guinness, along with Harp and Kilkenny, uses a U-system (European Sankey) coupler, not S-system. S-system covers beers like Heineken, Amstel, and Stella Artois. Check your specific keg's valve type before ordering, since the two are not interchangeable.
How do I tell if my import keg is S-system without guessing?
Match the brand to a known S-system list, or check the valve fitting directly against a coupler before ordering. When in doubt, contact us with the specific beer brand and we'll confirm the correct system before you order.
