The Wacker Neuson Washer is a genuine OEM component designed for the HI and HDR series indirect and direct-fired air heaters. Sourced directly from Wacker Neuson, this washer carries the same part specification as the original hardware installed at the factory. It is compatible with a wide range of HI-series models including the HI 110D, HI 200D, HI 300D, HI 400HD, and HI 90, as well as HDR-series radiant heaters such as the HDR 45, HDR 115, and HDR 155. When you order part number, you can be confident you are receiving an exact-fit replacement engineered to Wacker Neuson's own standards.
Key Features
- Genuine OEM Hardware Grade — Manufactured to Wacker Neuson's original dimensional and material specification, ensuring correct load distribution and clamping force for heater assembly hardware.
- Direct Drop-In Replacement — Matches the original mounting hole size and thickness of the factory-installed washer, allowing straightforward installation without re-drilling or shimming.
- Broad HI and HDR Series Coverage — Fits a wide range of Wacker Neuson indirect air heaters (HI 90, HI 110D, HI 120, HI 200D, HI 300D, HI 400HD, and HD variants) plus HDR 45, HDR 115, and HDR 155 radiant heaters.
- Maintains Fastener Integrity in Demanding Conditions — A correctly spec'd washer prevents fastener pull-through and surface damage on heater panels and frames, especially important where combustion heat and vibration are present.
- Fuel System and Combustion Assembly Safety — In heater applications, correctly rated hardware prevents loosening of critical fasteners near fuel and ignition components, supporting safe, code-compliant operation on the worksite.
A washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it bears against. By spreading clamping force over a wider area, it protects panel faces and housings from damage, prevents fasteners from working loose under vibration, and ensures a secure, stable assembly. In indirect and direct-fired air heaters like the Wacker Neuson HI and HDR series, hardware integrity is especially important because combustion heat and constant blower vibration place ongoing stress on every fastened joint. A missing, deformed, or undersized washer can allow fasteners to loosen over time, leading to misaligned panels, air or fuel leaks, or accelerated wear on surrounding components.
