The Wacker Neuson High Temp Gasket Tank is a genuine OEM component designed for the HI 770 XHD Indirect Air Heater series and the E3000 Ground Heater. Sourced directly from Wacker Neuson, this part meets the exact material and dimensional specifications of the original, ensuring a direct drop-in replacement with no guesswork. Confirmed fitment spans multiple HI 770 XHD configurations — including single-duct and dual-duct variants — as well as the Arctic Bear XHD and E3000 6kW Ground Heater models. When your heater is down, the is the part that gets it back to full operation fast.
Key Features
- High-Temperature Material Integrity — Engineered to withstand the sustained heat and thermal cycling demands of diesel indirect air heaters, maintaining a reliable seal under operating conditions.
- Genuine OEM Part — Manufactured to Wacker Neuson's original specification, so fit, function, and material grade match the part that came off the production line.
- Direct Drop-In Installation — Matches the original tank and gasket interface geometry exactly, allowing straightforward reinstallation without modification to mounting surfaces or hardware.
- Broad HI 770 XHD and E3000 Coverage — A single part number covers multiple HI 770 XHD duct configurations (1x16, 1x20, 2x12), the Arctic Bear XHD, and the E3000 Ground Heater, making it a practical stock item for fleets running Wacker Neuson heating equipment.
- Fuel System Seal Compliance — A properly seated high-temp gasket is critical in diesel-fired heating equipment; a degraded or incorrect gasket risks fuel weeping near the tank connection, making verified OEM material grade a genuine safety consideration.
- Verified Part Number Traceability — Part number 5100025820 is cross-referenced against Wacker Neuson's own parts documentation, giving you confidence you're ordering the correct component before the part even ships.
The high temp gasket tank assembly seals the junction between the fuel tank and the heater's combustion system, preventing fuel leaks while withstanding the elevated temperatures generated during continuous diesel-fired operation. In indirect air heaters like the HI 770 XHD, maintaining a sound seal at this connection is essential for consistent fuel delivery and safe operation — a deteriorated gasket can allow fuel vapor or liquid to escape, disrupting combustion and creating a potential hazard. Replacing a worn or damaged gasket tank with a genuine OEM unit restores the original sealed interface and returns the heater to safe, full-output performance.
