Key Features
- Genuine OEM Material Consistency — Manufactured to Wacker Neuson's original material grade and dimensional spec, ensuring the washer seats and distributes load exactly as intended in the assembly.
- Drop-In Replacement — Matches the original hole diameter, outer diameter, and thickness for direct installation without reworking mating hardware or fasteners.
- Confirmed Fitment — Compatible with HSH350 and HP252 hydronic surface heaters, including 50Hz HSH350 DG configurations.
- Proper Load Distribution — Maintains correct clamping force across fastened joints, protecting sealing surfaces and threaded connections from wear and damage over repeated thermal cycles.
- Corrosion and Heat Resistance — Built to withstand the elevated operating temperatures and moisture exposure typical of hydronic heating systems, helping the fastened connection stay secure through extended use.
A flat washer distributes the clamping load of a bolt or nut across a wider surface area, preventing fastener heads from pulling through or deforming the material they secure. In a hydronic surface heater like the HSH350 or HP252, where thermal expansion, vibration, and fluid pressure place ongoing stress on bolted connections, a correctly sized and properly rated washer is essential to maintaining joint integrity. A worn, undersized, or missing washer can allow fasteners to loosen prematurely, leading to fluid leaks or structural looseness in critical assemblies.
