The Wacker Neuson 5200016867 Exhaust Insulator is a genuine OEM component designed for the G25 and G50 series portable generators, covering Standard, Cold Weather, Extended Run, Custom, Mobile, 600V, and URI HVAC Tier 4 Final configurations, as well as the HIF 690 Flameless Air Heater. As a direct OEM replacement, part 5200016867 is manufactured to the exact material and dimensional requirements of the original, ensuring a drop-in installation with no guesswork. This insulator plays a critical role in exhaust system heat management, protecting surrounding components and maintaining safe surface temperatures during operation. If your G25 or G50 generator is showing signs of heat damage near the exhaust or the original insulator has cracked or deteriorated, replacing it with this genuine Wacker Neuson part restores the exhaust system to its intended operating condition.
Key Features
- Genuine OEM Heat Resistance — Manufactured from materials rated for continuous exhaust heat exposure, matching the thermal performance of the original part exactly.
- Direct-Fit Replacement — Engineered to the original exhaust outlet geometry of the G25 and G50 generator platforms for straightforward installation.
- Broad G-Series Compatibility — Fits a wide range of G25 and G50 configurations including Standard, Cold Weather, Extended Run, Custom, Mobile, 600V, and URI HVAC Tier 4 Final variants, plus the HIF 690 Flameless Air Heater.
- Protects Adjacent Components — A functioning exhaust insulator shields wiring, hoses, and enclosure panels from radiant heat — preventing secondary damage that a degraded insulator can cause.
- Safe Exhaust System Operation — Proper insulation is essential for maintaining safe exterior surface temperatures on enclosed generator sets; a cracked or missing insulator is a burn and fire risk that this genuine OEM part directly addresses.
The exhaust insulator wraps or shields the exhaust outlet or manifold section of the generator's engine, reducing the amount of radiant and conductive heat transferred to the surrounding generator enclosure, frame, and nearby components. On enclosed portable generator sets like the G25 and G50, managing exhaust heat is critical — without effective insulation, heat can degrade wiring harnesses, fuel lines, and structural panels over time, or create surface temperatures that pose a burn hazard to operators. When the insulator cracks, compresses, or falls away, those protections are lost and secondary damage to more expensive components often follows.
