The Vaillant 0020046863 Gas Pipe is a genuine replacement fuel line component designed to carry natural gas safely and reliably from the boiler’s gas inlet into the internal combustion system. This precision-formed pipe maintains correct gas routing and alignment with control valves and the burner, helping support stable combustion, responsive modulation and safe operation. A damaged, corroded or leaking gas pipe can cause pressure loss, unsafe conditions or ignition faults, so fitting the correct OEM part is essential for dependable performance and safety.

This gas pipe is compatible with Vaillant ecoTEC Plus VUW and ecoTEC Pro VUW series boilers that reference part number 0020046863 in their technical documentation. To ensure correct fitment and reliable operation, always verify that the part number matches your existing gas pipe or consult your boiler’s service information before installation, as gas pipe dimensions and connections vary between models and configurations.

Supplied ready for direct replacement, the 0020046863 Gas Pipe integrates with the boiler’s existing gas connections and mounting points without modification when installed by a qualified Gas Safe engineer. Choosing this genuine Vaillant component helps maintain secure gas delivery, supports efficient combustion and contributes to safe, consistent heating performance in compatible boilers.
