O-Ring 80151729 | High-Pressure Nitrile Rubber O-Ring for Hydraulic Rock Drills

High-Pressure Nitrile Rubber O-Ring for Hydraulic Rock Drills
Engineered for extreme underground mining conditions, this O-ring ensures reliable sealing in high-vibration hydraulic rock drill systems. Constructed from nitrile rubber (NBR) with Shore A 70 hardness, it withstands continuous dynamic loads while resisting abrasion and chemical corrosion in harsh environments .

Technical Specifications & Design
The O-ring adheres to AS568 standard dimensions (ID 25.4 mm x CS 3.53 mm) and ISO 3601-1 Class A tolerances, ensuring precise fit in hydraulic cylinder assemblies and drill rig components . Its zinc-plated surface treatment (12 μm thickness) passes 240 hours of salt spray testing (ISO 9227), providing long-term durability in wet or corrosive mining environments . The 20 MPa maximum working pressure (without backup ring) and -40°C to +125°C temperature range make it suitable for heavy-duty hydraulic applications .
