Couplers
Micro Matic, DSI and more
Options to meet your every need
Available for all common valve systems, our wide range of dispensing heads/keg couplers combine perfect compatibility with proven quality.
Starting with our basic models, we can assemble individualized ball shut-off valves, hose nozzles, lip valves, threaded or John Guest Push-Fit adapters, decompression valves, and more. We can even add your company logo to the handle, and under-counter versions are available for each system.
Our couplers are all DIN SK-approved and feature hygienic design, robust construction, solid metal handles and easy-to-maintain pistons. As standard, our piston connections come with G1/2 or G5/8 threads, and our gas connection with G1/2 or G5/8 male and G3/8 female threads.
