The Wacker Neuson is a genuine OEM Washer, Flat, 3/8 designed for a broad range of Wacker Neuson heating and climate equipment, including E3000 ground heaters, E2200 hydronic surface heaters, HI1000 and HI770 XHD indirect air heaters, HSH hydronic surface heaters, CUB series indirect fired air heaters, and associated hose handling and pump pack systems. As a direct OEM part, the is manufactured to the exact material and dimensional specifications called out in the original equipment design — ensuring correct load distribution and sealing wherever it is installed. This washer is confirmed to fit an extensive list of Wacker Neuson heating units across the E-series, HI-series, HSH-series, CUB-series, and Pureheat product families, making it a versatile service stock item for dealers and fleet operators alike.
Key Features
- OEM-Spec Material and Thickness — Manufactured to the exact dimensions and material grade specified by Wacker Neuson, ensuring correct clamping force and load distribution at every fastened joint.
- Direct-Fit Replacement — Sized at 3/8 to drop directly onto the existing fastener without modification, maintaining correct bolt torque and surface contact across the assembly.
- Broad Fitment Across Heating Families — Confirmed for E-series ground and hydronic surface heaters, HI-series indirect air heaters, HSH hydronic surface heaters, CUB indirect fired air heaters, Pureheat hydronic heaters, and associated pump and hose handling systems.
- Protects Mating Surfaces — Distributes fastener load across a wider area to prevent surface deformation, fastener pull-through, and loosening caused by vibration during extended heating operation.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number — 5000167730 — as referenced in the original service documentation and parts diagrams.
A flat washer serves as a bearing surface between a fastener head or nut and the material being fastened. By spreading the clamping load over a larger area, it prevents the fastener from pulling through or damaging softer substrates and keeps joints tight and secure over time. In heating equipment that operates under thermal cycling and vibration, a correctly specified washer also helps resist fastener loosening — a worn, missing, or incorrect washer can cause joint failure, fluid or air leaks at critical connections, and accelerated wear on the mating surfaces it was designed to protect.
