The Wacker Neuson Exhaust Flex Pipe G120 is a genuine OEM component designed for the G120 Mobile Generator series, including Cold Weather, Skid-Mounted, and Custom configurations. Sourced directly from Wacker Neuson, this part matches the original specification for a drop-in installation with no guesswork. Confirmed fitment spans the G120 Mobile Generator (Cold Weather), the G120 Skid-Mounted Mobile Generator, and the G120 Mobile Generator (Custom), making it the right choice across the full G120 lineup.
Key Features
- Genuine OEM Exhaust Integrity — Manufactured to the original wall thickness and alloy grade, ensuring correct exhaust flow and heat resistance specific to the G120 generator platform.
- Flexible Design for Vibration Absorption — The flex section accommodates engine movement and thermal expansion, protecting rigid exhaust components from stress cracking over extended run cycles.
- Broad G120 Series Coverage — Fits the G120 Mobile Generator (Cold Weather), G120 Skid-Mounted Mobile Generator, and G120 Mobile Generator (Custom) variants under a single part number.
- Direct OEM Replacement — Connects to existing exhaust mounting points using the original hardware layout, so installation follows the same procedure as the factory unit.
- Exhaust Sealing and Emissions Compliance — A correctly seated flex pipe prevents exhaust gas leaks that can compromise operator safety and cause the generator to fall outside emissions compliance requirements.
The exhaust flex pipe serves as the flexible connecting section within the generator's exhaust system, routing combustion gases away from the engine while absorbing vibration and allowing for slight movement between fixed exhaust components. Its flexibility is critical — without it, thermal expansion and engine vibration would place continuous stress on rigid exhaust joints, leading to cracks, exhaust leaks, and eventual failure. When this component deteriorates or develops a breach, exhaust gases can escape into the surrounding environment, creating both a safety hazard and a loss of back-pressure that can negatively affect engine performance on the G120 generator.
