The Wacker Neuson O-Ring is a genuine OEM sealing component designed for the EHB 7M, EHB 7/115, and EHB 7/230 series SDS-max electric demolition and rotary hammers. Sourced directly from Wacker Neuson, this O-Ring meets the exact material and dimensional specifications of the original part. It is confirmed to fit multiple EHB 7 variants across both 115V and 230V configurations, making it the correct choice when servicing any machine in this hammer family. Always cross-reference your machine's model number before ordering to ensure an accurate match.
Key Features
- OEM-Grade Sealing Material — Manufactured to the precise compound and compression rating specified for SDS-max demolition hammer internals, ensuring consistent sealing performance under high-cycle impact conditions.
- Drop-In Installation — Dimensioned to seat correctly in the original groove without modification, restoring the sealed interface exactly as intended during assembly.
- Broad EHB 7 Family Coverage — Fits the EHB 7M, EHB 7/115, and EHB 7/230 electric hammer models, covering both 115V and 230V variants across multiple machine configurations.
- Prevents Internal Contamination — A correctly functioning O-Ring keeps dust, debris, and moisture out of critical internal passages; a worn or extruded O-Ring can allow contaminants to reach lubricated components, accelerating wear.
- Genuine Wacker Neuson Part — Part number 5000104193 is supplied as a genuine OEM component, carrying the same part number used in the original factory assembly documentation.
An O-Ring in an SDS-max electric demolition hammer serves as a precision seal between internal assemblies, preventing lubricant from escaping and stopping dust and debris from entering sealed chambers. In a high-impact tool like the EHB 7 series, these seals are subjected to repeated shock loads and heat cycles that cause gradual hardening, compression set, or cracking over time. When an O-Ring fails, lubricant loss and contamination ingress can lead to accelerated wear on the tool's internal drive components, making timely replacement an important part of routine hammer maintenance.
