The Wacker Neuson Gasket is a genuine OEM component designed for the E1250S and E1250B hydronic heaters as well as the HSH380S and HSH380B hydronic surface heater series. Sourced directly from Wacker Neuson, this gasket delivers the exact material grade, compression characteristics, and dimensional accuracy required by the original design. Part number covers a broad range of configurations across these heater families, including LP/NG, diesel, and natural gas/propane variants — with and without generator options. Confirming your model number before ordering ensures a direct, hassle-free installation.
Key Features
- OEM Material and Compression Spec — Manufactured to the original seal material and thickness specification, ensuring the correct compression load and leak-free seating on mating surfaces.
- Drop-In Installation — Matches the original gasket profile exactly, seating cleanly between mating faces without trimming or reworking the surrounding components.
- Broad Heater Fitment — Compatible with E1250S, E1250B, HSH380S, and HSH380B models across LP/NG, diesel, and natural gas/propane configurations, with and without generator packages.
- Maintains Fluid and Pressure Integrity — A correctly seated gasket keeps the hydronic circuit sealed under operating temperature and pressure; a worn or failed gasket leads to fluid leaks and loss of heating efficiency.
- Fuel and Fluid System Safety — In hydronic and combustion-adjacent circuits, a properly rated OEM gasket is critical to preventing uncontrolled fluid or combustion gas escape that could create a safety hazard on the jobsite.
A gasket forms a pressure-tight, leak-resistant seal between two mating surfaces — typically a cover, housing, or manifold joint — preventing fluid, coolant, or combustion gases from escaping the circuit. In hydronic surface heaters like the E1250 and HSH380 series, maintaining this seal is essential to keeping the heating loop pressurized and operating at the correct temperature output. When a gasket deteriorates, compresses unevenly, or fails, it allows fluid to weep or escape the joint, which can reduce system pressure, compromise heating performance, and potentially create hazardous conditions around fuel or heated fluid lines.
