The Wacker Neuson Fender Washer is a genuine OEM component designed for the HSH and E-series hydronic surface heaters, including the HSH700G, HSH650, E1100, E2200, E3000 ES, and S3000 series. As a direct OEM replacement, part is manufactured to the same specification as the original hardware, ensuring proper load distribution and a secure, flush fit at every fastener point. This washer is confirmed across a wide range of hydronic surface heater configurations — from standard ground heaters to generator-equipped and lift-bail variants — so you can order with confidence regardless of your specific unit.
Key Features
- Genuine OEM Material Integrity — Produced to Wacker Neuson's original material and dimensional spec, giving you the correct bearing surface area and thickness that the fastener joint was engineered around.
- Wide Bearing Surface — The oversized flange of a fender washer distributes clamping load across a broader area, preventing pull-through and panel deformation on sheet metal and composite surfaces common to hydronic heater enclosures.
- Broad HSH and E-Series Compatibility — Fits HSH350, HSH650, HSH700G, E1100, E2200, E3000 ES, and S3000 hydronic surface heater models, covering both ground heater and surface heater configurations.
- Drop-In Hardware Replacement — Matches the original hole diameter and outer flange dimensions, so it installs directly without modification to existing fastener locations or mating hardware.
- Supports Structural Integrity of the Assembly — Worn, corroded, or undersized washers can allow fasteners to loosen over time; replacing with the correct OEM part maintains proper joint tension throughout the heater's service life.
A fender washer is a flat fastener component with a larger-than-standard outer diameter relative to its center hole. This oversized flange spreads the load of a bolt or screw head across a wider surface area, which is especially important when fastening through thin sheet metal, soft materials, or pre-formed openings where a standard washer could pull through under vibration or mechanical stress. In hydronic surface heaters — equipment that operates under thermal cycling and field handling — maintaining secure, properly loaded fastener joints is essential to keeping panels, brackets, and hose connections in place. A missing or damaged fender washer may allow fasteners to work loose, leading to rattling components, compromised enclosure integrity, or accelerated wear at the fastener point.
