Wacker Neuson 5000152863 Rear Duct Insulator Right Side

The Wacker Neuson Rear Duct Insulator Right Side is a genuine OEM component designed for the G25 series portable generators. Sourced directly from Wacker Neuson, this insulator is confirmed to fit the G25 skid-mounted mobile generator, G25 mobile generator skid-mounted cold-weather configuration, and related G25 variants. Correct fitment and OEM construction ensure this part integrates exactly as the original, maintaining the thermal management integrity of the generator exhaust duct system.

Key Features

• Genuine OEM Thermal Rating — manufactured to the same material grade and heat-resistance specification as the original, ensuring the insulator performs correctly within the G25 duct assembly.
• Right-Side Specific Design — this insulator is position-specific to the right side of the rear duct; using the correct side designation prevents improper installation and ensures a flush, secure fit.
• G25 Generator Series Coverage — compatible with skid-mounted, standard mobile, and cold-weather G25 configurations, covering the core variants in this generator family.
• Thermal Containment Performance — a properly functioning duct insulator directs exhaust heat away from surrounding components; a deteriorated or missing insulator can allow heat buildup that stresses adjacent parts and reduces generator service life.
• Direct OEM Replacement — drops into the existing rear duct assembly using the original mounting points, requiring no adaptation to the surrounding structure.

The rear duct insulator on the G25 generator serves as a heat barrier within the exhaust duct system, containing and directing hot exhaust gases away from temperature-sensitive components housed in the generator enclosure. On the right-side rear duct specifically, the insulator helps maintain consistent airflow management and protects the surrounding structure from radiant heat damage. When this insulator deteriorates, cracks, or goes missing, heat transfer to adjacent components increases, which can accelerate wear on nearby wiring, mounts, and enclosure panels — making timely replacement important for the long-term health of the generator.
