The Wacker Neuson is a genuine OEM O-Ring 87 X 4-70 Shore designed for the EH 9, EHB 10, and EHB 11 series electric breakers and demolition hammers. Sourced directly from Wacker Neuson, this part meets the exact material and dimensional specifications required for proper sealing within these tools. It fits a wide range of voltage variants across the EH 9, EHB 10, and EHB 11 families, including 110V, 115V, 230V, and 240V configurations. Confirming your machine number against the fitment list before ordering ensures a direct, no-hassle installation.
Key Features
- 70 Shore Hardness Rating — The 70 Shore durometer rating delivers the correct balance of compression and resilience for the sealing demands of electric demolition hammers, maintaining an effective barrier under cyclic impact loads.
- Correct 87 x 4 mm Cross-Section — Dimensioned to seat precisely in the designed groove within the EH 9, EHB 10, and EHB 11 housings, ensuring full circumferential contact without distortion on installation.
- Genuine OEM Part — Manufactured to Wacker Neuson's material specification, this O-ring matches the compound and hardness of the original, supporting consistent sealing performance over the tool's service life.
- Broad Series Compatibility — Fits EH 9 BL, EH 9 BLM, EHB 10, EHB 11 BL, EHB 11 BLM, and EHB 11 BLS variants across multiple voltage configurations, making it a practical stock item for fleets running multiple electric breaker models.
- Sealing Integrity Protects Internal Components — A failed or deteriorated O-ring allows contaminants and moisture into the hammer's internal mechanism, accelerating wear on critical moving parts. Replacing it promptly restores the tool's internal protection.
An O-ring in an electric demolition hammer serves as a static or dynamic seal between housing sections or internal assemblies, preventing dust, debris, and moisture from entering the tool's mechanism. In high-vibration tools like the EH 9 and EHB 11 series, O-rings are subject to constant compression cycling and can harden, crack, or take a permanent set over time. When an O-ring fails, contamination reaches bearings, gears, and the percussion mechanism, leading to accelerated internal wear and reduced tool performance.
