Run an eight-beer selection from your walk-in cooler to the bar with the Lupulus II 8-product beer trunk line. This insulated assembly contains eight 3/8" I.D. multilayer barrier beverage tubes and two glycol circulation tubes for commercial long-draw draft systems.
The barrier tubing helps protect beer flavour and aroma through low flavour migration and low gas permeability. A smooth inner surface helps limit deposits inside the product lines, while circulating glycol removes heat picked up along the route to the dispensing tower.
Built for Multi-Product Draft Systems
This configuration provides eight separate beverage paths for bars, restaurants and brewery taprooms. Each product tube is marked with a colour stripe and printed identification, making it easier to follow a line from its keg connection to the correct faucet during installation and service.
A blue glycol supply tube and a red return tube form the cooling loop within the bundle. Both glycol tubes have a 3/8" inside diameter and remain separate from the beverage lines.
Insulation and Taped Jacket
The trunk is enclosed in 19 mm insulation to help reduce heat gain outside the refrigerated storage area. An aluminium foil and cling wrap layer surrounds the tubing assembly, with black PVC tape forming the protective outer jacket.
Insulate and seal the connections at the cooler and tower so that exposed sections do not become warm spots. Route and support the trunk without sharp bends, compressed insulation or kinked tubing.
Key Benefits
- Eight beverage paths: Connect an eight-product draft selection through one insulated trunk.
- Multilayer barrier tubing: Helps preserve beer flavour and aroma by limiting flavour migration and gas permeation.
- Smooth product tube interior: Helps reduce deposit buildup as part of a regularly cleaned draft system.
- Separate glycol supply and return: Keep coolant circulating alongside the beverage lines.
- 19 mm insulation: Helps reduce heat entering the trunk between the cooler and the bar.
- Traceable product lines: Colour stripes and printed markings make individual tubes easier to identify.
- Protective outer wrap: Black PVC tape covers the insulated bundle.

Selecting the Right Trunk Line
Select this model when your system calls for eight beverage lines with 3/8" I.D. barrier tubing. Before ordering, check the full route length, elevation changes and available installation space. Beverage line resistance and dispensing pressure must be balanced, and the glycol power pack must provide sufficient cooling and circulation for the installation.
Explore our beer trunk lines for other capacities and tubing sizes, or browse our glycol chillers to plan the cooling side of your system. Product line stripe colours may vary.
