The Wacker Neuson Flat Washer is a genuine OEM component designed for HSH350, Pureheat, E1100, and CH5000 series hydronic surface heaters and hydronic air heaters. Sourced directly from Wacker Neuson, this flat washer is manufactured to the same specifications as the original hardware installed at the factory. It is confirmed compatible across multiple configurations within these heater families, including oil burner, gas burner, diesel, and generator-equipped variants. Whether you are completing a scheduled service or replacing worn hardware, part number ensures a consistent, correct-spec repair.
Key Features
- Genuine OEM Hardware Grade — Manufactured to Wacker Neuson's original material and dimensional tolerances, ensuring correct load distribution and clamping performance in hydronic heater assemblies.
- Direct Drop-In Replacement — Matches the original fastener stack-up exactly, seating flush against mating surfaces without any rework or shimming.
- Broad Heater Family Compatibility — Fits HSH350, Pureheat (oil burner, gas burner, and diesel variants), E1100, and CH5000 series machines, covering a wide range of Wacker Neuson hydronic heating equipment.
- Protects Critical Joints — A correctly sized flat washer distributes fastener load evenly across mounting surfaces, preventing surface damage, loosening under vibration, and premature joint failure in demanding heating environments.
- Verified OEM Part Number — Order with confidence using part number 5000167755, cross-referenced directly against Wacker Neuson's parts catalog for these heater models.
A flat washer serves as a load-spreading interface between a fastener — such as a bolt or nut — and the surface it bears against. In hydronic heater assemblies, where components are subject to thermal cycling, vibration, and fluid pressure, a washer in poor condition can allow fasteners to loosen, damage mounting surfaces, or compromise the integrity of sealed joints. Replacing a worn or missing flat washer with the correct OEM part helps maintain proper clamp load and keeps the assembly performing as intended over the long term.
