The Wacker Neuson is a genuine OEM O-Ring designed for the EHB 7 series electric demolition hammers, including the EHB 7M, EHB 7/115, and EHB 7/230 models. As a direct OEM replacement, this O-Ring is manufactured to the exact material and dimensional specifications required by Wacker Neuson for use in these SDS-max rotary demolition hammers. Sourcing the correct OEM seal for this application ensures the internal assembly maintains its intended sealing integrity across the full operating range of the tool. Confirm your model number against the fitment list before ordering to ensure this is the right part for your machine.
Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's exact compound and hardness specifications, ensuring correct compression and sealing performance inside the EHB 7 hammer assembly.
- Drop-In Replacement — Seats directly into the original groove position with no trimming or modification to the housing or adjacent components.
- Broad EHB 7 Series Coverage — Compatible with EHB 7M, EHB 7/115, and EHB 7/230 variants, covering both 115V and 230V SDS-max electric demolition hammer configurations.
- Preserves Internal Lubrication — A correctly seated O-Ring keeps grease and lubricant contained within the hammer mechanism, preventing dry-running wear on internal components.
- Genuine Wacker Neuson OEM Part — Supplied as part 5000104199 directly within the Wacker Neuson OEM parts program, so you're getting the same component installed at the factory.
- Electrical Safety Relevance — Maintaining proper sealing in an electric demolition hammer helps prevent contaminant ingress near internal electrical and mechanical components, supporting safe, intended operation.
An O-Ring in a rotary demolition hammer serves as a precision seal between internal assemblies, keeping lubricating grease retained within the gear and impact mechanism while blocking dust, debris, and moisture from entering the housing. In an SDS-max tool like the EHB 7 series, the hammer mechanism operates under significant cyclic stress, and a deteriorated or incorrectly sized O-Ring will allow grease to migrate out of the mechanism and contaminants to work their way in. Over time, this leads to accelerated wear on internal components, reduced impact energy, and potential failure of the hammer drive system.
