The Wacker Neuson Breather Tube is a genuine OEM component designed for ML440 Light Towers and MG5 series Portable Generators. Sourced directly from Wacker Neuson, this part meets the same specifications as the tube installed at the factory, ensuring a correct, trouble-free installation. It covers a broad range of ML440 and MG5 configurations — including MG5, MG5d, and MG5sd variants — making it the right choice whether you are servicing a light tower or a portable generator on a busy job.
Key Features
- Genuine OEM Venting Integrity — Manufactured by Wacker Neuson to maintain correct crankcase or fuel system venting pressure, preventing pressure buildup that can compromise seals and engine performance.
- Direct Drop-In Replacement — Matches the original routing path and connection points of the stock tube, so installation requires no trimming, adapting, or rerouting of existing lines.
- Broad ML440 and MG5 Series Coverage — Confirmed fitment across ML440 Light Tower configurations and the full MG5 Portable Generator family, including MG5d and MG5sd models.
- Protects Engine Longevity — A properly functioning breather tube prevents oil contamination and maintains clean airflow through the engine breathing circuit, keeping internal components operating within design limits.
- Verified Part Number Traceability — Part number 5000404118 is the Wacker Neuson OEM reference, giving you confidence that you are ordering the correct tube for your specific machine configuration.
A breather tube manages the ventilation of internal engine or fuel system gases, allowing built-up pressure to escape in a controlled way rather than forcing it past gaskets and seals. Without a functioning breather tube, excess pressure can cause oil leaks, accelerated seal wear, and contamination of the air intake — all of which lead to costly engine damage over time. Replacing a cracked, collapsed, or blocked breather tube restores proper pressure balance and keeps the engine running cleanly.
