The Wacker Neuson Breather Tube is a genuine OEM component designed for the G70, G100, and G120 generator series, including Custom, Standard, Cold Weather, Extended Run, Hertz, and URI HVAC configurations. As a direct OEM part, it is manufactured to the same specification as the original, ensuring a correct, drop-in installation with no guesswork. This breather tube is confirmed to fit across the full T4i-compliant range of Wacker Neuson portable generators, making it the trusted choice for service technicians and fleet maintenance crews. Keep part number on hand to minimize service interruptions during scheduled maintenance or field repairs.
Key Features
- OEM Crankcase Venting Specification — Manufactured to the original flow and dimensional tolerances required for proper crankcase pressure relief in Wacker Neuson generator engines.
- Direct-Fit Replacement — Engineered to connect at the original routing points, allowing straightforward installation without trimming, adapting, or rerouting.
- Broad Generator Series Coverage — A single part number covers G70, G100, and G120 models across Custom, Standard, Cold Weather, Extended Run, Hertz, and URI HVAC variants.
- Protects Engine Longevity — A functioning breather tube keeps crankcase pressure balanced; a cracked or blocked tube can force oil past seals and introduce contaminants into the air intake, accelerating engine wear.
- Emission System Integrity — On T4i-certified engines, correct crankcase ventilation is part of the emissions compliance design; using the correct OEM tube supports the intended closed-loop system function.
A breather tube routes blow-by gases from the engine crankcase back into the air intake system, preventing pressure from building up inside the engine. This controlled venting keeps oil seals intact and ensures combustion gases are managed rather than vented to atmosphere. When a breather tube cracks, collapses, or becomes clogged, crankcase pressure rises — pushing oil past gaskets and seals, causing oil consumption, rough running, and potential engine damage over time.
