The Wacker Neuson Washer is a genuine OEM component designed for the Pureheat, E1100, E1250, and HSH380 series hydronic surface heaters. As a direct OEM replacement, it is sourced to the same specifications as the original part, ensuring a proper fit within the assembly it serves. This washer is confirmed compatible across a broad range of Wacker Neuson hydronic heating units, covering oil burner, gas burner, LP/NG, and diesel-powered configurations. Having the correct on hand keeps maintenance straightforward and helps restore the machine to full operational condition without guesswork.
Key Features
- Genuine OEM Tolerancing — Manufactured to Wacker Neuson's original dimensional specification, so the washer seats, seals, and loads exactly as intended in the fastened joint or fluid connection.
- Drop-In Replacement — Matches the original mounting profile and hardware interface, allowing direct installation without reworking adjacent components.
- Broad Hydronic Heater Compatibility — Fits Pureheat, E1100, E1250B, E1250S, E1250P, HSH380B, and HSH380S series units across LP/NG, diesel, and oil burner variants.
- Maintains Fastener Joint Integrity — A worn or missing washer can cause uneven clamping load, fastener loosening, or fluid weepage; replacing it with the correct OEM part restores the designed clamping surface and load distribution.
- Fuel and Fluid System Safe — Used within hydronic heating equipment that handles fuel and heated fluid circuits, so correct material grade and dimensional accuracy are essential to a leak-free assembly.
A washer functions as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it clamps against. In hydronic surface heaters, washers are used throughout the burner, fluid circuit, and structural assemblies to spread clamping force evenly, prevent fastener pull-through, and protect sealing surfaces from damage. When a washer is deformed, corroded, or missing entirely, the fastener joint can lose clamping torque over time, leading to loose fittings, fluid leaks, or vibration-related failures. Replacing a damaged washer with the correct OEM part — part number 5000168342 — restores the designed joint integrity and keeps the heater operating as intended.
