The Wacker Neuson Seal is a genuine OEM component designed for the HI750, HI900, and HI260 series indirect-fired air heaters. As a direct OEM replacement, this seal is manufactured to the exact specifications required by Wacker Neuson, ensuring a correct, leak-free fit in the applications it was engineered for. Fitment covers a broad range of HI-series configurations including diesel, natural gas, LP, and dual-fuel variants across both trailer-mounted and skid-mounted units. Keep a on hand as a service item wherever HI-series heaters are operating in demanding cold-weather environments.
Key Features
- Genuine OEM Sealing Material — Manufactured to Wacker Neuson's exact material and compression specifications for this heater family, ensuring proper sealing performance under thermal cycling and pressure.
- Drop-In Replacement — Engineered to install directly into the same seat and interface as the original, with no re-machining or adaptation needed at the sealing surface.
- Broad HI-Series Compatibility — Fits multiple configurations across the HI750, HI900, and HI260 indirect-fired air heater families, including diesel, natural gas, LP, and surge-brake-equipped models.
- Maintains Combustion and Airflow Integrity — A correctly seated seal prevents combustion gas or heated air from bypassing the intended flow path, keeping heat output efficient and consistent on the jobsite.
- Fuel System Safety Relevance — Seals in fuel-carrying or combustion-adjacent systems are critical to safe heater operation; using a genuine OEM part ensures the correct material grade for the temperatures and media involved.
A seal in an indirect-fired air heater serves as a barrier between pressurized or high-temperature zones within the unit, preventing leakage of combustion gases, fuel, or heated air past critical joints and interfaces. When a seal degrades — through heat cycling, compression set, or chemical exposure — it can allow gases or fluids to escape their intended path, reducing heating efficiency and potentially creating a safety hazard. Replacing a worn seal with the correct OEM part restores the integrity of that interface and keeps the heater operating as designed.
