Wacker Neuson 5200008472 Silicone Reducer Hose 3-2.25

The Wacker Neuson is a genuine OEM Silicone Reducer Hose 3-2.25 designed for the G100, G120, G150, and G180 series portable generators. As a direct OEM replacement, part is manufactured to the same specifications as the original component installed at the factory, ensuring a correct, trouble-free installation. This hose services an extensive range of G-series generator configurations, including skid-mounted custom builds, mobile generator variants, cold-weather packages, and switchable 600-volt Tier 3 units. When your air or coolant routing depends on a reliable transition between differing hose diameters, the Wacker Neuson delivers the fit and durability the job demands.

Key Features

• Silicone Construction for High-Temperature Resilience — Silicone compound resists heat, ozone, and compression set better than standard rubber hose, maintaining a secure seal even under the sustained thermal cycling of continuous generator operation.
• Correct 3-to-2.25-Inch Step-Down Profile — The molded reducer geometry matches the OEM connection points exactly, seating flush against both the larger and smaller barbs or couplings without trimming or shimming.
• Broad G-Series Generator Coverage — Confirmed fitment across G100, G120, G150, and G180 generator families, spanning skid-mounted custom, mobile, cold-weather, and switchable 600-volt Tier 3 configurations.
• Genuine OEM Part — Same Source as the Original — Sourced directly through Wacker Neuson's authorized parts network, so the hose wall thickness, durometer rating, and end diameters match what left the factory.
• Prevents Airflow or Coolant Loss at the Transition Point — A cracked or collapsed reducer hose disrupts the intake or cooling circuit, causing overheating or power loss; replacing it with 5200008472 restores the sealed, full-flow path the generator relies on.

A reducer hose bridges two sections of an air intake or cooling circuit that operate at different diameters, maintaining a sealed, uninterrupted flow path between them. In generator applications, even a small gap or collapse at this transition point can allow unmetered air into the intake tract or interrupt coolant circulation, leading to rough running, overheating, or automatic shutdown. Over time, heat cycles and vibration cause the hose material to harden, crack, or deform at the step-down shoulder — replacing a worn reducer hose promptly keeps the engine's thermal and air management systems functioning as intended.
