The Lupulus II 12-product beer trunk line is designed for commercial draft installations where flavour protection matters alongside temperature control. It contains twelve 5/16" I.D. multilayer barrier beverage tubes and four 3/8" I.D. polyethylene glycol tubes, enclosed in an insulated, taped bundle.
Lupulus II product tubing has low gas permeability and low flavour and odour migration to help preserve beverage quality during dispensing. Its smooth inner surface helps limit deposits inside the lines, while the separate glycol circuit helps keep beer cold on its way from the walk-in cooler to the taps.
Built for Multi-Product Draft Systems
With twelve independent beverage lines, this trunk accommodates a varied beer selection in bars, brewery taprooms and restaurants. Each product tube has a colour stripe and printed identification, helping technicians trace the correct line when connecting kegs, cleaning the system or servicing a faucet.
Four glycol tubes run through the bundle: two blue supply lines and two red return lines. They carry chilled glycol alongside the beverage tubes and back to the power pack as part of the system’s cooling circuit.
Insulation and Taped Jacket
A 19 mm insulation layer helps reduce heat gain between the refrigerated keg storage area and the dispensing point. Aluminium foil and cling wrap surround the internal assembly, and a black PVC tape jacket protects the outside of the insulated bundle.
To maintain cooling through the complete installation, joints and exposed tubing at both ends also need to be insulated and sealed. The trunk should be supported along its route and installed without crushing the insulation or kinking the tubes.
Key Benefits
- Multilayer barrier product tubing: Low gas permeability and low flavour and odour migration help protect beverage quality.

Selecting the Right Trunk Line
Choose this configuration when your installation requires twelve product lines with multilayer barrier tubing. Confirm that the 5/16" beverage line diameter suits the planned run length, vertical lift and dispensing pressure. Size the glycol power pack and circulation equipment for the complete cooling route.
