CA-AG01-AWT · A system keg coupler · original CADCouplers for type A and type S are on the shelf
Several thousand are in the European warehouse, in the versions for type A and type S, for Germany and Poland. We source the other systems and fit them on request. Ex stock, from one box.
The right coupler for every system
From our range or built entirely to your specification.
The range for the A, S, D, G and M systems: German style with double lip valve, models with CO₂ adapter and with pressure relief valve. Every image is rendered from the model’s original CAD data and shows the coupler with the lever open.
Pressure relief valve on request: we can fit any coupler with a pressure relief valve (PRV) on request.
For special fittings and features
In addition to our standard range, we build keg couplers for other fitting types and with special features: for example the type A with a ball valve on the beer outlet, as is common in France and Belgium, or a coupler for U fittings. We build any coupler you want.
Metal lever handle with a large print area: on request, we can supply any coupler with this metal lever handle, whose large surface has room for your own brewery name.
Serial couplers
Serial couplers are built for connecting kegs in series: several kegs are linked one after the other and dispensed like one large container. We offer serial couplers for all spear types and in a range of configurations.
Connections to order
All couplers can be delivered with the connections of your choice, in your preferred diameter: hose tails straight or bent, or quick-connect fittings, whether John Guest or another system. Different threads on the CO₂ side and the beer side are possible too, and we can fit either type of handle. We produce all connections in-house. Just tell us briefly what you need. We look forward to your enquiry and to designing your coupler together with you.

Questions about keg couplers
Which keg coupler fits my keg?
The keg coupler must match the system of the spear: A on A, G on G, M on M, S on S and D on D. You can identify the system from the spear, for example by the round or triangular flange or by the Sankey head without a flange.

Yes. Type A and G keg couplers are tested under DGUV Test NV 24815 (SK 448-004), type S and D under NV 24814 (SK 448-003), in each case with and without valve to DIN 6650-5, valid until 7 July 2029.
