The Wacker Neuson Washer is a genuine OEM component designed for the E1250S, E1250P, E3000, and HSH380 series hydronic surface heaters and ground heaters. As a factory-sourced part, it meets the exact dimensional and material tolerances specified for these machines, ensuring a flush, secure fit within the assembly. This washer is a direct replacement for worn or damaged units across a broad range of Wacker Neuson heating equipment configurations, including LP/NG, diesel, and generator-equipped variants.
Key Features
- OEM-Grade Material Consistency — Manufactured to the same hardness and dimensional tolerance as the original, ensuring correct load distribution and surface protection at fastener points.
- Drop-In Replacement — Matches the original bore diameter and outer profile exactly, seating correctly without modification across all listed machine configurations.
- Broad Heating Equipment Compatibility — Fits E1250S and E1250P hydronic heaters, E2200 and E3000 ground heaters, and HSH380B/HSH380S hydronic surface heaters in standard, diesel, LP/NG, and generator-equipped variants.
- Preserves Fastener and Housing Integrity — A correctly sized washer prevents fastener pull-through and surface damage on heating system components, maintaining clamping force over repeated thermal cycles.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5100024257 is verified against the original equipment bill of materials for these heater families.
A washer functions as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it bears against. In heating equipment like hydronic surface heaters and ground heaters, washers help maintain consistent clamping force across components that experience repeated thermal expansion and contraction during operation. When a washer wears, deforms, or goes missing, the fastener can lose torque retention, leading to loosened assemblies, vibration-related damage, or compromised sealing at critical joints.
