Key Features

• Genuine OEM Dimensional Accuracy — Manufactured to the exact thickness and inner/outer diameter tolerances specified for Wacker Neuson heating and hydronic equipment assemblies, ensuring consistent clamping load and surface protection.
• Drop-In Hardware Replacement — The 1/2 inch sizing installs directly onto existing fastener positions across all compatible models with no rework or sizing adjustments needed.
• Broad Heating Equipment Coverage — Fits E-series ground heaters (E1100, E2200, E3000, E3000ES, E5000), HI770XHD and HI1000 indirect air heaters, HSH-series hydronic surface heaters, S3000 units, Pureheat hydronic heaters, and multiple HHS hose handling system configurations.
• Protects Fastener Joints Under Thermal Cycling — A properly fitted flat washer distributes clamping force across the mating surface, preventing fastener pull-through and surface damage that can develop when heating equipment is repeatedly cycled through high and low temperatures.
• Stocked OEM Part Number — Ordering by verified part number 5000167728 eliminates the guesswork of sourcing generic hardware and confirms you are installing the exact component specified in the Wacker Neuson parts catalog.

A flat washer serves as a load-distribution interface between a fastener — typically a bolt or nut — and the surface it clamps against. By spreading the clamping force over a wider area, the washer prevents the fastener head from pulling through or damaging the material beneath it and helps maintain consistent joint tension over time. On heating equipment such as ground heaters, hydronic surface heaters, and indirect air heaters, where assemblies are exposed to repeated thermal expansion and contraction, using the correct OEM-specified washer size and grade is essential. A missing, undersized, or worn-out washer can lead to loose joints, vibration damage, or fluid and air pathway misalignment — all of which compromise equipment reliability during critical cold-weather work.
