The Wacker Neuson Hose Assembly 20mm x 400mm is a genuine OEM component designed for G100 and G120 series mobile generators. As a direct factory replacement, this hose assembly carries the correct inner diameter, wall thickness, and end fittings to seat and seal exactly as the original. It covers a wide range of G100 and G120 configurations, including standard mobile, cold weather, skid-mounted custom, and Canadian Transport-compliant variants. When a cooling or fluid transfer hose begins to crack, soften, or leak, swapping it with the correct OEM part like the restores the fluid circuit to full operating spec.
Key Features
- OEM-Matched Hose Construction — manufactured to the same inner diameter, length, and wall specification as the original, ensuring a proper seal under operating pressure and temperature cycles typical of generator coolant or fuel circuits.
- Drop-In Fitment for G100 and G120 Generators — the 20mm bore and 400mm routed length match the original hose routing, so end connections locate and clamp without modification.
- Broad G100 and G120 Series Coverage — verified fit across standard mobile, cold weather, skid-mounted custom, high-voltage switchable, and Transport Canada-compliant generator configurations.
- Fluid Circuit Integrity — a sound hose maintains stable flow through the coolant or ancillary fluid system; a cracked or collapsing hose risks overheating, fluid loss, and unplanned shutdowns on the job.
- Genuine Wacker Neuson OEM Part — sourced directly through the Wacker Neuson parts supply chain, carrying the correct part number 5000179370 and backed by OEM quality assurance.
A hose assembly of this type routes coolant, fuel, or ancillary fluid between key components inside the generator enclosure, maintaining steady flow volume and pressure throughout the operating cycle. The specified 20mm internal diameter and 400mm length are engineered to match the exact routing path within the G100 and G120 generator frames, so the hose sits under the correct tension without kinking or bearing undue stress at the end fittings. When a hose degrades — through heat cycling, age, or abrasion — it can weep or fail outright, starving downstream components of fluid and triggering thermal protection faults or engine damage.
