What drink are you going to dispense
A beer line does not have exactly the same requirements as a line for wine, soft drink, syrup, BiB or gas. The type of beverage determines material, barrier, cleaning and routing.

Food‑grade tubing for dispensing beverages by tap
Tubing is an essential part of any dispensing installation. It carries beverage, gas or recirculation water and determines factors as important as hygiene, service stability, ease of assembly and system maintenance. In this guide we bring together the most useful criteria for choosing between Poly, Lupulus II, Crystal PVC, tubing for Bag in Box, python, python bundle and other solutions related to the run between the keg, refrigeration and the tap.

How to correctly choose the tubing for a beverage installation
Choosing the right tube is not just about picking a size. The key is first to identify what will run through the line, what temperature it will work at, whether the run will be short or remote, whether there will be recirculation of cold water and what type of fittings or accessories the installation will use. The tube that works well for gas is not always the most suitable for product, and a very flexible tube is not always the best choice when stability, hygiene or the technical behaviour of the line are the priority.
In simple installations it is usually enough to clearly distinguish the product line, the gas line and, where present, the chilled‑water line. In more complete installations, solutions such as individual python bundle, contact python, bath python and different python formats appear to improve temperature preservation and service stability.
How the system is cooled
A short run without recirculation is not the same as a remote installation with cold water or a flooded solution where thermal control along the run is critical.
What space do you have for installation
Length, bends, ease of routing and access for assembly matter just as much as the tube material itself.
Practical tip
Before buying, it’s worth thinking through the entire installation run, not just a single section. That helps you choose the product tube, the gas tube and, if there’s recirculation, the water or chilled recirculation section more effectively.
Types of tube and when each one is usually of interest
Within a tap‑dispensed beverage installation, several types of tube can coexist. Some are designed for the main product line, others for gas and others for recirculating water or technical runs where flexibility is the priority. This difference is important because it helps you buy better and avoid common compatibility or application mistakes.
Poly / polyethylene tube
Poly is a very versatile solution for beverage and gas installations. It’s a good fit when you’re looking for a multipurpose food‑grade tube, with good compatibility with quick‑connect fittings and a reasonable balance between cost, functionality and ease of integration. It’s often a very logical base for standard lines, homebrewing, gas and setups where you want a reliable, practical solution.
Lupulus II Tube
Lupulus II is a more technical option, especially interesting when the installation requires a higher-grade line for beer and other chilled beverages. It’s a family aimed at installations where hygiene, service stability, the tube’s internal behavior and a more premium assembly feel matter more.
Crystal PVC for water and chilled recirculation
Crystal PVC stands out for its great flexibility and transparency. In a dispensing installation it is especially useful for water circulation, chilled recirculation and runs where space is tight or there are sharp bends. It is also practical when you want quick visual inspection of the liquid passing through the tube.
For product lines with higher technical demands, it’s usually more sensible to look at other families that are more beverage-oriented. That’s why, on a public page, it’s best to present it mainly as a solution for water, cooling and technical sections of the system.
Tube for Bag in Box
Very useful in wine, vermouth, soft drink, syrup systems or solutions compatible with Bag in Box. When the priority is a clean, tidy and easy-to-maintain installation, it deserves its own category within the tubing system.
Gas tube
The gas line must be chosen on its own merits. Although it sometimes shares sizes or connectors with other parts of the installation, it should not be treated as just another product line.
Technical tubes and special solutions
In more advanced projects, families with more barrier, reinforcements, greater elasticity or specific configurations for python bundles, python and remote runs may come into play.
Which tube usually fits best for each application
| Application | What is usually prioritized | Solutions that usually fit better |
|---|---|---|
| Beer per tap | Hygiene, stability, line behaviour and ease of maintenance | Lupulus II, Poly in certain runs, contact python, bath python, python solutions |
| CO₂ / N₂ gas | Compatibility, pressure, safety and clean assembly | Poly, Flexlayer, braided and dedicated gas lines |
| Wine, vermouth, BiB and soft drinks | Neutrality, installation order and system compatibility | Poly, Bag in Box, technical lines depending on application |
| Recirculation / irrigation water | Flexibility, run length and visual control | Crystal PVC, Poly and lines integrated in python or trunk line |
| Homebrewing and Corny Keg | Compatibility, ease of work and scalability of the setup | Poly, Lupulus II, gas tubing and quick-connect accessories |
A well-designed installation usually combines several types of tube
In many setups, one solution is used for beverage, another for gas and another for water or recirculation. Approaching it this way usually improves service and makes future expansions or repairs easier.
Python, trunk line and cooled runs
When the installation is no longer a short run and needs to maintain the temperature from the cooler to the point of service, solutions such as pitón and python come into play. This is where the complete system becomes important: product lines, cold recirculation water, insulation and internal organization of the run.
Single python
Interesting when you need to protect a specific line or handle a cooled run without going to a more complex solution.
Contact python
Very useful for keeping lines cold in remote installations or in runs where the temperature along the route directly affects the final service.
Bath or flooded python
Designed for runs where thermal stability is a priority and a more constant temperature is needed between the cooler and the tap.
On the market there are also different families of python, including flood, tube‑in‑tube, cabled, taped and other technical formats for beverage installations. This helps to understand that not every “python bundle” or “python” solves the same problem: the right solution depends on the run, the required thermal performance and the space available in the installation. :contentReference[oaicite:1]{index=1}
Practical comparison: Poly vs Lupulus II vs Crystal PVC
| Family | General profile | When it is usually of interest | What to keep in mind |
|---|---|---|---|
| Poly | Versatile, standard and multipurpose | General beverage and gas lines, homebrewing and setups with quick-connect fittings | It’s a very good base for many projects, although it won’t always be the most technical option for demanding installations |
| Lupulus II | More technical and geared towards demanding installations | Beer, chilled drinks and systems where you want a higher‑spec line and better overall performance | It becomes very attractive when the priority is to level up the main product line. |
| Crystal PVC | Very flexible, transparent and easy to install | Water, cooled irrigation and technical runs with limited space | It’s best to present it mainly as a solution for water circulation and cooling, not as the first choice for more demanding product lines. |
When to move up to a more technical solution
When the installation needs a more refined product line, better internal behaviour and a setup more geared towards demanding service.
When a more standard solution makes sense
For gas lines, homebrewing, general runs or setups where compatibility and practicality come first, a base like Poly usually works very well.
How to correctly plan a beverage tubing installation
In a dispensing installation, the tube should not be chosen as an isolated piece. The right approach is to think through the entire run from the point of origin to the point of service: product line, gas line, possible chilled water irrigation or recirculation, type of insulation, python bundle or python system and compatibility with fittings, quick connectors and accessories.
When the setup is well designed, the result is usually more stable: better temperature retention, fewer issues, a cleaner installation and easier maintenance. That’s why, before buying, it’s worth checking not only the tube material, but also the type of beverage, the length of the run, the need for cooling and the space available for the setup.
Product line
It is the part of the system that most affects hygiene, barrier, preservation and the behaviour of the drink during service.
Gas line
It must be chosen on its own merits, taking into account pressure, fitting compatibility and circuit safety.
Irrigation and recirculation
In refrigerated or remote installations, the cold‑water circuit is part of the overall performance and affects the choice of tubing.
What you should check before buying
- What drink you’re going to dispense and at what temperature.
- Whether the tube will be for product, gas or water recirculation.
- If the installation is short, remote, with python or trunk line.
- What internal and external diameter the system actually needs.
- Which connectors, fittings or clamps you are going to use.
Common mistakes when choosing tubing for beer and beverages
- Choosing the tube only by size without thinking about the line’s actual function.
- Treat the product line, the gas line and the chilled‑water line in the same way.
- Prioritizing flexibility alone when the setup needs more stability or better technical performance.
- Do not check compatibility with quick-connect fittings, barbs, clamps and accessories.
- Ignoring the full run between keg, machine, python, tower and tap.
- Planning a remote setup without properly assessing insulation, recirculation and temperature control.
Frequently asked questions about food‑grade tubing for beverage dispensing
Which tube is best for draft beer?
It depends on the run and the type of installation. For more demanding systems, a more technical solution like Lupulus II can be very interesting. For more general setups or gas lines, Poly usually fits very well.
Are the gas tube and the beverage tube the same thing?
Not necessarily. It’s worth clearly distinguishing the product line, the gas line and the recirculation or cold-water section, because they’re not always chosen with the same criteria.
What is Crystal PVC tube used for in a dispensing installation?
In a beverage installation, Crystal PVC is used mainly for water, chilled recirculation and runs where flexibility and transparency help with assembly and visual inspection. For product lines with higher technical demands, it’s worth considering other tube families more focused on beverages.
When is it worth using a contact python?
When you need to keep the product cold along the run between refrigeration and point of service, especially in remote or bar installations where the temperature along the route matters a lot.
What’s the difference between contact python and bath python?
The contact python helps keep lines cold through bundling, insulation and recirculation. The bath or flooded python is designed to maintain temperature more consistently on runs where that stability is a priority.
Can I use Poly with quick-connect fittings?
Yes. One of Poly’s usual advantages is precisely its good compatibility with quick-connect fittings in many setups.
What is a python in beverage dispensing?
It is a technical bundle of product lines and, depending on the design, water or cooling lines, grouped and insulated to better maintain temperature along the run between the machine and the tap.
Can you help me choose the right tubing for my installation?
Yes. If you tell us which beverage you’re dispensing, what run you have, which machine or system you use and whether you need a gas, water or python line, we can give you much better guidance.
Would you like us to help you choose the right tubing for your draft beverage setup?
