The Wacker Neuson is a genuine OEM Assembly Bottle 6 Qt. 1/2 Nptf designed for the G-series portable generator line, covering models G25, G50, G70, G85, G100, G120, G125, G150, G160, G180, and G240. Sourced directly from Wacker Neuson, this part meets the same design and material standards as the original component installed at the factory. Fitment spans a wide range of skid-mounted and mobile generator configurations, including standard, cold weather, extended run tank, and custom variants. Verify your model number against the compatibility list to confirm fitment before ordering.

Key Features

  • Genuine OEM Construction — Manufactured to the original material and dimensional specifications of the Wacker Neuson G-series generator coolant/fluid system, ensuring the bottle seats, seals, and connects exactly as intended.
  • 6 Qt. Capacity with 1/2 NPTF Port — The 6-quart volume and standard 1/2 NPTF threaded fitting allow direct connection to existing lines without adapters or modifications to the fluid circuit.
  • Broad G-Series Compatibility — Fits G25 through G240 mobile and skid-mounted generators across standard, cold weather, custom, extended run tank, and Tier 3/Tier 4 configurations.
  • Maintains Proper Fluid Management — A correctly functioning reservoir bottle keeps fluid levels stable and visible, supporting consistent generator operation across extended run cycles and cold-weather deployments.
  • Direct OEM Replacement — Part number 5000159404 cross-references directly to the original assembly, so technicians can confirm the correct part before the machine goes back into service.

The Assembly Bottle 6 Qt. 1/2 Nptf serves as the fluid reservoir in the generator's coolant or fluid management circuit. It holds the reserve volume needed to maintain proper fluid levels during operation, with the 1/2 NPTF port providing a secure, leak-resistant connection to the associated lines. When this bottle cracks, leaks, or loses its seal at the port fitting, fluid levels drop and the generator becomes vulnerable to overheating or system faults — making prompt replacement critical to keeping the unit running reliably through long job cycles.
