Wacker Neuson 5000058132 O-Ring 118 x 3-70 Shore NBR

The Wacker Neuson is a genuine OEM O-Ring 118 x 3-70 Shore NBR designed for the EH 22 series electric demolition breakers, including the EH 22/220, EH 22/400, EH 22/400 WSZ, EHL 22/400 WSZ, and EH 22/230 60Hz models. As a direct OEM replacement, the is manufactured to the exact dimensional and material specifications required by Wacker Neuson for this application. NBR (nitrile butadiene rubber) compound at a 70 Shore hardness provides the correct balance of compression resistance and sealing performance for the operating environment of these electric breakers. Confirm your model number before ordering to ensure a correct fitment match.

Key Features

• OEM-Spec NBR Compound — 70 Shore hardness nitrile rubber delivers the correct compression set resistance and fluid compatibility required for sealed breaker components.
• Exact Dimensional Match — 118 x 3 mm profile seats directly into the OEM groove without trimming, stretching, or re-seating adjustments.
• Broad EH 22 Series Coverage — Fits EH 22/220, EH 22/400, EH 22/400 WSZ, EHL 22/400 WSZ, and EH 22/230 60Hz electric breakers across multiple voltage configurations.
• Sealing Integrity Under Load — A correctly installed O-ring maintains internal pressure boundaries and keeps contaminants out; a worn or torn O-ring leads to lubrication loss and accelerated internal wear.
• Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, ensuring the material grade, hardness, and geometry match the original engineering intent for these electric breakers.

An O-ring is a precision sealing element that sits in a machined groove and forms a pressure-tight barrier between mating surfaces or moving components. In an electric demolition breaker like the EH 22 series, O-rings are used throughout the internal assembly to contain lubrication, exclude dust and moisture, and maintain the pressure differential that drives the hammering mechanism. When an O-ring degrades — through heat cycling, chemical exposure, or simple age — it loses its ability to seal, which can allow lubricant to escape and contaminants to enter, leading to internal wear and reduced breaking performance. Replacing a worn O-ring promptly with the correct part is one of the most cost-effective ways to restore full function and protect the surrounding components.
