This 12-product beer trunk line provides an insulated connection between refrigerated keg storage and a remote dispensing area. Twelve food-grade polyethylene beverage tubes share the bundle with four glycol circulation tubes, keeping the product lines together along the installation route.
Available with 5/16" or 3/8" I.D. beverage tubing, it gives installers a choice of product line sizes for the planned draft system. This PE configuration is a practical option for bars, restaurants and taprooms that need twelve separate beverage lines with glycol cooling.
Built for Multi-Product Draft Systems
Each beer travels through its own product tube from the cooler towards its assigned faucet. Colour stripes and printed identifiers help technicians organise the connections and locate individual lines when cleaning, replacing fittings or investigating a dispensing problem.
The glycol circuit uses two blue supply tubes and two red return tubes. These run alongside the beverage lines, allowing chilled glycol to absorb heat along the route and carry it back to the power pack.
Insulation and Taped Jacket
The tubing assembly is wrapped in aluminium foil and cling wrap and enclosed in 19 mm insulation. A black PVC tape jacket covers the outside, helping protect the insulated bundle during handling and installation.
Cooling performance also depends on the finish at each end of the trunk. Insulate and seal exposed connections, and support the run without flattening the insulation or forcing the tubing through tight bends.
Key Benefits
- Twelve individual beverage lines: Accommodate a varied draft selection through one shared installation route.
- Choice of product tubing diameter: Select 5/16" or 3/8" I.D. to suit the system design.
- Food-grade polyethylene tubing: A practical product line material for standard commercial draft installations.
- Four glycol circulation lines: Provide two supply and two return paths for coolant alongside the beverage tubes.
- 19 mm insulation: Helps limit heat gain outside the walk-in cooler.
- Colour-coded product tubes: Printed markings and colour stripes help identify the correct line during installation and service.
- Protective taped jacket: Black PVC tape covers the insulated assembly.

Selecting the Right Trunk Line
Choose the product tubing diameter as part of the draft system’s pressure and flow calculations. The 5/16" and 3/8" options have different flow resistance, so the choice should account for run length, elevation changes and the required dispensing pressure. Match the glycol power pack and circulation equipment to the cooling demands of the complete route.
