## Summary description

Copper refrigeration double tube by Vaillant with 1/4" and 1/2" line diameters, supplied with insulation and integrated e-bus wiring, length 5 meters. Designed for connecting heat pump or outdoor unit models VWL 35 to VWL 55, it provides refrigerant piping and communication wiring in one preassembled set for faster installation and leak-resistant refrigeration connections.

## Long description

Copper refrigeration double tube by Vaillant combines two refrigerant lines with factory-applied insulation and integrated e-bus wiring in a 5 m preassembled set. It is designed to connect outdoor units and heat pumps in the VWL 35–VWL 55 range, providing the liquid and gas refrigerant circuits together with communication cabling to simplify on-site installation and reduce the number of separate components required for system hookup.
Advantages
The preassembled double tube reduces installation time by delivering both 1/4" and 1/2" refrigerant lines ready for connection, with continuous insulation to limit thermal loss and condensation. Integrated e-bus wiring allows immediate electrical communication between indoor and outdoor units without separate cable routing. Using factory-assembled refrigeration tubing supports leak-resistant joints and consistent line spacing, improving reliability and speeding up commissioning.
Suitable for
 Connecting Vaillant VWL 35 to VWL 55 series outdoor units and heat pumps
 Retrofit or new installations where a pre-insulated, pre-wired refrigerant connection is preferred
 Installations requiring compact routing of refrigerant and communication lines between outdoor and indoor components
Key specifications
 Copper refrigerant tubing: two parallel lines with nominal diameters 1/4" and 1/2"
 Length: 5 meters of continuous preassembled piping
 Thermal insulation: factory-applied on the refrigerant lines to reduce heat gain and condensation
 Communication wiring: integrated e-bus cable included within the assembly
 Configuration: double tube assembly suitable for liquid and gas refrigerant circuits with combined wiring
How to use
Position the preassembled double tube between the outdoor unit and the indoor heat pump components, ensuring the correct orientation of the 1/4" and 1/2" lines for liquid and gas connections. Cut and flare or prepare the copper ends as required by the specific Vaillant service instructions for VWL 35–VWL 55 models, then make the refrigerant connections following refrigeration best practices and local regulations. Connect the integrated e-bus wiring to the designated terminals on both units, observing polarity and shielding recommendations described in the equipment manuals. Perform pressure and leak tests after assembly and evacuate and charge the system according to manufacturer guidance.
Usage recommendations
Use qualified HVAC or refrigeration technicians for installation. Keep the factory insulation intact where possible; repair or replace damaged insulation before commissioning. Verify compatibility with the specific VWL 35–VWL 55 indoor/outdoor combination and follow Vaillant service documentation for torque values, brazing or flaring procedures, and electrical connections.
