The Wacker Neuson Exhaust Gasket is a genuine OEM component designed for the G25 and G20 series portable generators, covering a wide range of configurations including standard, cold weather, custom, extended run, T4i, T4F, and 600V switchable variants. As a direct OEM part, is manufactured to the exact material grade and dimensional tolerances required by Wacker Neuson for proper exhaust sealing on this generator family. Whether you're servicing a skid-mounted G25 on a jobsite or maintaining a G20 mobile unit, this gasket drops into place with no guesswork. Keeping an accurate part number like on hand ensures you're ordering the correct seal for your specific machine configuration.
Key Features
- OEM-Grade Sealing Material — Manufactured to the exact thermal and compression specifications required for the G25/G20 exhaust system, ensuring a gas-tight seal under operating temperatures.
- Direct-Fit Replacement — Matches the original bolt pattern and flange profile, allowing straightforward installation without trimming or shimming.
- Broad G25 and G20 Coverage — Compatible across standard, cold weather, custom, extended run, T4i, T4F, and 600V switchable configurations of the G25 series, plus G20 mobile generator variants.
- Prevents Exhaust Leakage — A failed or deteriorated exhaust gasket allows hot exhaust gases to escape at the joint, leading to increased noise, fume exposure, and potential heat damage to surrounding components.
- Emissions and Safety Compliance — A properly sealed exhaust path is essential for maintaining T4i and T4F emissions compliance; a compromised gasket can cause a generator to run outside its certified parameters.
The exhaust gasket forms a heat-resistant seal between the engine's exhaust port and the exhaust manifold or outlet pipe, preventing combustion gases from escaping before they reach the exhaust system. On portable and skid-mounted generators like the G25 and G20, this seal is subject to repeated thermal cycling — expanding and contracting with every start and shutdown — which gradually degrades gasket material over time. When the gasket fails, exhaust gases leak at the joint, producing elevated noise levels, carbon buildup around the exhaust flange, potential fume hazards near the operator, and in some cases overheating of adjacent engine components.
