Wacker Neuson 5002001341 O-Ring 70 X 3 70 Sh

The Wacker Neuson O-Ring 70 X 3 70 Sh is a genuine OEM sealing component designed for the BH 22, BH 23, BH 24, BH 40, BH 55, BH 65, EH 22, EH 23, EH 24, EH 25, EH 27, EH 50, EH 65, EH 70, and EH 75 series gasoline and electric breakers. Sourced directly from Wacker Neuson, this part matches the exact material grade, durometer, and dimensional tolerances specified for the original application — ensuring a drop-in fit with no guesswork. The carries broad fitment coverage across both petrol and electric breaker lines, making it a reliable stock item for fleet operators, rental companies, and service technicians managing multiple Wacker Neuson units. Replacing a worn or damaged O-Ring promptly protects internal components from contamination and fluid loss that can lead to accelerated wear or tool failure.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's specified 70 Shore hardness and 70 x 3 mm cross-section, delivering the correct compression set resistance for breaker service conditions.
• Direct Seat Replacement — Dimensioned to seat precisely in the original O-Ring groove without trimming or shimming, restoring the factory seal interface on first installation.
• Wide Series Compatibility — Fits BH 22, BH 23, BH 24, BH 40, BH 55, BH 65 gasoline breakers and EH 22 through EH 75 electric breakers across multiple voltage and tool-holder configurations.
• Leak Prevention at High Cycle Rates — A correctly installed O-Ring maintains the pressure boundary inside the breaker mechanism; a degraded seal allows ingress of debris and loss of hydraulic or pneumatic pressure, causing erratic impact performance.
• Fuel and Fluid Compatibility — Formulated to resist degradation from the lubricants and sealing fluids present in Wacker Neuson breaker assemblies, extending service intervals between seal inspections.

An O-Ring is a circular elastomeric seal that sits in a machined groove between two mating surfaces or around a moving component, preventing the passage of fluids, gases, or fine particulate matter across that boundary. Inside a gasoline or electric demolition breaker, O-Rings maintain the integrity of lubricated chambers and pressure passages that drive the reciprocating piston mechanism — the system responsible for delivering impact energy to the tool shank. When an O-Ring hardens, cracks, or takes a permanent set from heat and mechanical cycling, the seal fails, allowing lubricant to escape and contaminants to enter; the result is accelerated internal wear, inconsistent striking power, and ultimately a breaker that requires major service far ahead of its normal maintenance schedule.
