G System Keg Coupler – NSF Certified Draft Beer Dispensing Solution – C715
The G System keg coupler is an essential component for tapping kegs and dispensing fresh beer. NSF Certified for hygiene and safety, it is designed to connect securely to compatible kegs, allowing smooth gas infusion and controlled beer dispensing for a perfect pour every time.
People commonly call the G System a “Grundy” coupler, and several international breweries such as Grolsch, Boddingtons, and Caffrey’s use this design widely. Its unique valve profile features a circular face with three flat cut sections, ensuring a secure and accurate keg connection.
This coupler features a robust brass body with a chrome-plated finish for durability and corrosion resistance, paired with an SS304 stainless steel probe for long-lasting hygienic performance. The ergonomic lever-style handle ensures easy locking and unlocking during keg changes, making it highly efficient for commercial use.
Krome G System keg couplers deliver reliable performance in bars, restaurants, and breweries while dispensing a wide range of beers. Compatible with popular brands such as Anchor Steam (50L kegs), Boddingtons, Caffrey’s, Carling, Fuller’s, Grolsch, Old Speckled Hen, Tennents, and Watneys, this coupler delivers consistent performance in demanding environments.
