The Wacker Neuson Gasket is a genuine OEM component designed for the E1250S and E1250P hydronic heaters as well as the HSH380S hydronic surface heater series. Sourced directly from Wacker Neuson, this gasket delivers the exact material composition and dimensional tolerances required to maintain a proper seal within the heating system. It is compatible across multiple configurations, including LP/NG and diesel-fueled variants of the E1250S, E1250P, and HSH380S. When you need a dependable, drop-in replacement, the is the correct OEM part for the job.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original material specification, ensuring the gasket compresses and seals correctly under the thermal and pressure cycling conditions typical of hydronic heating systems.
- Direct-Fit Replacement — Matches the original profile and bolt-hole pattern exactly, seating flush without trimming or shimming during reinstallation.
- Broad Fitment Coverage — Compatible with the E1250S (LP/NG), E1250P (LP/NG and Diesel), HSH380S (Natural Gas/Propane), and HSH380S (Diesel with Generator) — a single part number covering the full hydronic heater family.
- Leak Prevention at the Source — A compromised gasket in a hydronic heater allows fluid or combustion gases to escape the sealed circuit, leading to heat loss, fluid contamination, and potential safety concerns; a fresh OEM gasket restores the integrity of that seal.
- Fuel-System and Combustion Safety Compliance — As a sealing component within a fuel-fired heating system, using the correct OEM gasket material is essential to maintaining safe operation across all rated fuel types and operating temperatures.
A gasket forms a compressed, leak-proof barrier between two mating surfaces inside the heater — typically between a heat exchanger, burner assembly, or fluid manifold and its housing. In a hydronic surface heater, this seal must hold reliably against both elevated temperatures and fluid pressure; even a minor leak can allow heat transfer fluid or combustion gases to escape, reducing heating efficiency and creating a potential hazard. When a gasket deteriorates, cracks, or takes a permanent set from repeated heat cycling, it must be replaced promptly to restore safe, efficient heater operation.
