The Wacker Neuson Gasket is a genuine OEM component designed for the HSH380S and HSH380B hydronic surface heaters, E1250S and E1250P hydronic heaters, E2200 and E3000 ground heaters, and HI1000 and HI1000DGM indirect air heaters. Sourced directly from Wacker Neuson, this gasket carries the same part number and material specification as the original, ensuring a consistent seal without guesswork. It fits a broad range of fuel configurations across these series, including natural gas, propane, LP/NG, and diesel variants. If your unit is showing signs of leakage, gas bypass, or poor heating efficiency, the Gasket is the correct OEM replacement to restore the seal.
Key Features
- Genuine OEM Sealing Material — Manufactured to the same material grade and compression specification as the original, ensuring proper sealing performance under the thermal and pressure cycles these heaters generate.
- Drop-In Replacement — Matches the original gasket profile exactly, seating correctly without trimming or shimming during reassembly.
- Broad Series Compatibility — Fits HSH380S, HSH380B, E1250S, E1250P, E2200, E3000, HI1000, and HI1000DGM models across LP/NG, propane, and diesel fuel configurations.
- Restores Combustion and Heat Efficiency — A failed or compressed-out gasket allows combustion gases or heat to bypass the intended path, reducing heater output and driving up fuel consumption. A fresh OEM gasket brings the unit back to designed output.
- Fuel System Integrity — On combustion heaters, a compromised gasket can allow uncontrolled gas migration. Using the correct OEM gasket maintains the sealed integrity of the fuel and combustion pathway.
A gasket forms a compression seal between mating surfaces in the heater's combustion or fluid circuit, preventing gases, fluids, or heat from escaping the intended flow path. In hydronic and indirect-fired heaters like these Wacker Neuson models, gaskets are subjected to repeated heating and cooling cycles that gradually cause them to compress, harden, or crack. When a gasket fails, the result is typically a visible leak, a drop in heating output, unusual combustion smells, or difficulty maintaining operating temperature — all signs that the seal needs to be replaced promptly to keep the heater running safely and at full capacity.
