The Wacker Neuson Flat Washer is a genuine OEM component designed for a broad range of Wacker Neuson ground heaters, hydronic surface heaters, indirect air heaters, and related heating system accessories. As a direct OEM replacement, this flat washer is sourced and supplied to Wacker Neuson's original specifications, ensuring correct material grade, dimensional accuracy, and proper load distribution across fastened joints. It is confirmed to fit the E3000, E2200, E5000, HI770XHD, HSH350, HSH650, HSH700, and Pureheat series, along with pump packs, heat exchangers, and mobile drying system configurations. Keeping a genuine fastener hardware component like the on hand means you can complete routine service or repair work on your heating equipment without delays caused by incorrect or undersized hardware.
Key Features
- OEM-Specified Material and Dimensional Accuracy — Manufactured to Wacker Neuson's original tolerances, ensuring the correct load-bearing surface area and material grade for heating system fastener joints.
- Drop-In Hardware Replacement — Matches the original washer's bore diameter, outer diameter, and thickness for straightforward installation without modification to existing hardware configurations.
- Broad Heating Equipment Fitment — Compatible across the E3000, E2200, E5000, HI770XHD, HSH, Pureheat, Arctic Bear HD/XHD, and associated pump pack and heat exchanger models.
- Protects Fastened Surfaces Under Thermal Cycling — In heating equipment subject to repeated heat and vibration cycles, a correctly sized flat washer distributes clamp load evenly, preventing surface damage and fastener loosening over time.
- Genuine OEM Part — Supplied as an authentic Wacker Neuson replacement, backed by the same part number — 5000167788 — used in original equipment assembly.
A flat washer is a simple but critical fastener component used throughout heating and construction equipment assemblies. Its primary role is to distribute the load of a bolt or nut over a wider surface area, protecting the material being fastened from damage and helping maintain consistent clamping force. In equipment like ground heaters and hydronic surface heaters that experience repeated thermal expansion and vibration, a worn, undersized, or incorrect washer can allow fasteners to work loose or cause surface deformation — leading to leaks, misalignment, or component failure. Using the correct OEM-specified washer for the application ensures the joint performs as designed throughout the service life of the equipment.
