The Wacker Neuson Flat Washer is a genuine OEM component designed for a wide range of Wacker Neuson heating, ground thawing, and hydronic surface heating equipment, including the E3000, E2200, E1100, E5000, HI 770 XHD, HSH350, HSH650, HSH700, CUB400, and CUB700 series, as well as Pureheat hydronic heaters, heat exchangers, pump packs, and hose handling systems. Sourced directly from Wacker Neuson, part number meets the exact material and dimensional standards of the original hardware used in production. This washer is a direct replacement for the factory-installed component, ensuring correct load distribution and fastener retention across the assemblies it supports. With broad fitment coverage spanning ground heaters, indirect air heaters, hydronic surface heaters, and ancillary systems, keeping a supply of on hand is a practical choice for fleet operators and service technicians working across multiple Wacker Neuson heating product lines.
Key Features
- OEM-Grade Material Consistency — Manufactured to Wacker Neuson's original hardness and dimensional tolerances, ensuring correct load distribution under fastener clamp loads in heating system assemblies.
- Drop-In Hardware Replacement — Matches the original hole diameter, outer diameter, and thickness spec of the factory washer, seating correctly against mating surfaces without modification.
- Broad Heating Equipment Fitment — Compatible with E-series ground and hydronic surface heaters, HI 770 XHD indirect air heaters, CUB400 and CUB700 skid and portable heaters, HSH hydronic surface heaters, heat exchangers, pump packs, and hose handling systems.
- Protects Fastener Integrity — A properly fitted washer prevents fastener pull-through, surface galling, and loosening under vibration — common failure modes in equipment exposed to repeated heating and cooling cycles.
- Genuine Wacker Neuson OEM Part — Supplied as part of Wacker Neuson's official service parts program, with part number 5000167729 verified against production assembly records.
A flat washer serves as a bearing surface between a fastener — such as a bolt or nut — and the component being secured. By spreading the clamping load over a wider area, it prevents the fastener head or nut from pulling through or damaging softer materials, and helps maintain consistent clamping force over time. In heating equipment like ground heaters, hydronic surface heaters, and indirect air heaters, fastener integrity is critical across panels, fluid connections, and frame assemblies that are regularly subjected to thermal expansion, vibration, and field servicing. A worn, undersized, or incorrect washer can lead to fastener loosening, surface damage, or fluid system leaks — making correct replacement hardware an essential part of any service or reassembly job.
