John Guest Drinks Tube

LLDPE tubing is a core component in modern drinks dispense systems, carrying beverages, potable water and gas between equipment throughout pubs, bars and commercial beverage installations. John Guest LLDPE tubing is designed specifically to work with push-fit connectors, allowing installers to build reliable dispense systems quickly while maintaining a clean and professional installation.

Within draught beer systems, tubing is commonly used to connect kegs, regulators, couplers and taps. It is also widely used in beverage equipment such as coffee machines, vending machines, water filtration units and reverse osmosis systems. Because these systems often operate in busy commercial environments, the tubing must be durable, flexible and compatible with food and beverage applications.

John Guest LLDPE tubing is manufactured from non-contaminating materials and is suitable for potable liquids, foodstuffs, air, vacuum and inert gas applications. It is commonly used for beer lines, water supply lines and gas lines within drinks dispense systems. The tubing is also available in multiple colours, allowing installers to easily identify different lines within complex systems such as python bundles or cellar installations.

The tubing works seamlessly with John Guest push-fit fittings, valves and accessories, enabling tool-free installation and easy maintenance. Installers simply cut the tubing square and push it into the fitting to create a secure, leak-tight connection. This makes it particularly useful in environments where systems may need to be modified or serviced regularly.

Typical tube sizes used in drinks dispense systems include 1/4", 5/16" and 3/8" outside diameter tubing, which are commonly used across beer lines, gas lines and water supply lines in commercial beverage equipment.

LLDPE stands for Linear Low-Density Polyethene. It is a durable plastic material commonly used for beverage tubing because it provides improved strength and flexibility compared with traditional polyethylene tubing. This material is widely used in drinks dispense systems, water filtration installations and beverage equipment.

In many pubs and bars, beer must travel from the cellar to the bar tap. When the distance between these points is significant, the beer lines are often installed inside a beer python system.

A beer python is an insulated bundle that contains several beverage lines along with cooling lines that maintain the correct serving temperature. LLDPE tubing is frequently used for these beer lines because it is flexible enough to route through the building while maintaining a reliable connection to fittings and equipment. As tubing is available in different colours, installers can clearly identify beer lines, gas lines and water feeds when working on complex installations.

LLDPE tubing offers several advantages when used in beverage dispense systems, such as:

• Flexible installation: The tubing is easy to route around equipment and through cellar installations.
• Push-fit compatibility: Designed to work with John Guest push-fit fittings for fast, tool-free connections.
• Food-grade materials: Suitable for potable water and beverage applications.
• Colour identification: Multiple tubing colours help identify different beverage and gas lines.
• Durability: Stronger than traditional low-density polyethene tubing and suitable for a wide range of beverage applications.

What tubing is used for beer lines?

Beer lines commonly use food-grade polyethene or LLDPE tubing. This type of tubing is flexible, durable and suitable for carrying beverages in commercial dispense systems. It is widely used in pubs, bars and breweries because it works with push-fit connectors and can be installed quickly without specialist tools.

What size tubing is used in beer dispense systems?

• 1/4" OD tubing
• 5/16" OD tubing
• 3/8" OD tubing

These sizes are typically used for beer lines, water supply lines and gas lines, depending on the system design and equipment being connected.

Can LLDPE tubing be used for water and gas lines?

Yes. LLDPE tubing can be used for a range of applications within drinks dispense systems including potable water lines, beverage lines and inert gas lines used in dispense equipment. However, it is important to ensure that the tubing size and pressure ratings match the system requirements.

How often should beer lines be replaced?

Beer lines should be inspected regularly and replaced if they become damaged, discoloured or contaminated. In busy pub environments, tubing may be replaced periodically as part of routine maintenance to maintain beverage quality and system hygiene. Routine inspection is recommended to ensure that tubing remains in good condition and free from leaks or damage.

LLDPE tubing is an essential component of modern drinks dispense systems, providing a flexible and reliable way to transport beverages, water and gas between equipment. Compatible with push-fit fittings and available in multiple sizes and colours, this tubing makes it easier to install, maintain, and service beer dispense systems, python lines and beverage equipment across pubs, bars and commercial hospitality environments.
