Beer hose 7mm or 10mm – which diameter is the right one?
When choosing the right beer hose, the diameter is a crucial factor. A particularly common question is: 7 mm or 10 mm beer hose – which is better? The answer depends on your dispensing system and the desired flow rate.
A beer hose with a 7 mm inner diameter is ideal for short runs and low beer flow rates. It reduces foam formation and ensures controlled dispensing—ideal for smaller dispensing systems or home use. A beer hose with a 10 mm diameter, on the other hand, is primarily used in professional applications or for longer lines. This allows more beer to flow simultaneously—a significant advantage for larger events or the catering industry.
Please note, however, that a hose diameter that is too large can lead to increased carbonation loss, which can make the beer taste flat. Therefore, it's important to match the beer hose diameter precisely to your needs. For dispensing systems with medium consumption, we generally recommend 7 mm; for long lines or high dispensing volumes, we recommend 10 mm.
Buying a beer hose for a dispensing system – what you should consider
When purchasing a beer hose for your dispensing system, you should consider more than just the price. Important criteria include material quality, diameter, connection compatibility, and the intended application.
When it comes to beer dispensing hoses, we distinguish between PVC, silicone, and special hoses for CO₂ systems. For private use, a transparent beer hose with a diameter of 7 mm is often sufficient, while more robust versions starting at 10 mm are used in commercial applications. Trautmeyer's high-quality models are neutral in taste, flexible, and food-safe—perfect for any dispensing system.
The right beer hose connection is also particularly important. Depending on the system, you may need different diameters or thread types. Our product range includes both individual parts and complete sets – from hoses and beer hose connectors to CO₂ connections.
Our tip: When ordering, make sure you choose the correct length and allow for a small reserve if necessary – especially for under-counter dispensing systems or pipe runs with angles.
Beer hose connection & thread: What is important?
A secure and leak-proof beer hose connection is crucial for the functionality and hygiene of your dispensing system. Leaks or air in the system can lead to beer loss and reduced quality. Therefore, it's important to choose the right beer hose threads and connectors—matched to the tap, keg connection, or CO₂ line.
Different standards are used depending on the system. Plug-in connections, such as the John Guest beer hose, are particularly popular, as they simply connect by plugging it in. This option offers safety and saves time during setup and cleaning.
Alternatively, there are screw connections, which are used primarily in professional systems. In such cases, it is essential that the beer hose connector precisely matches the hose diameter—be it 7 mm or 10 mm—and the thread.
Also, ensure the hoses are securely clamped: Hose clamps or special quick-release couplings provide additional support and prevent pressure loss. This is especially crucial for CO₂ lines, as the system pressure must be kept constant.
If you are unsure which system is suitable for you, our customer service will be happy to advise you or recommend a coordinated complete set.
Cleaning and maintaining beer hoses – keeping beer enjoyment hygienic
Regularly cleaning your beer hose is essential if you want to achieve consistently high-quality beer and hygienically perfect tapping results. Hop, yeast, or sugar residues provide ideal breeding grounds for germs – and can significantly impair the taste of your beer.
A beer hose should be thoroughly cleaned after every intensive use, but at least once a week, depending on the frequency of use. Cleaning adapter sets that flush the entire line system under pressure are particularly effective for this purpose – ideally when combined with a food-safe cleaning agent.
For permanently installed or hard-to-reach lines, we recommend foam cleaning devices that connect directly to the keg connection. Don't forget to regularly clean connectors, taps, and CO₂ lines as well—these are areas where residues often accumulate.
