The O-Ring (Part No. 0663214300) is a precision-engineered sealing component specifically designed for Hydraulic Rock Drills—workhorse machinery in mining, quarrying, construction, and rock excavation projects where reliable performance under extreme conditions is non-negotiable. As a critical element of the hydraulic system, we craft this O-Ring to address the unique challenges of hydraulic rock drill operations, including high pressure, constant vibration, exposure to hydraulic fluids, abrasive dust, and fluctuating temperatures ranging from freezing outdoor environments to heat generated by continuous drilling.
We manufacture this O-Ring from high-grade nitrile rubber (NBR) as standard—with silicone, Viton®, and EPDM options available for specialized applications. It delivers industry-leading resistance to hydraulic oil, mineral oil, grease, and chemical contaminants commonly found in mining and construction sites. Its robust composition ensures exceptional wear resistance, tear strength, and compression set resistance, meaning it maintains its shape and sealing integrity even after prolonged use under high hydraulic pressure (up to 350 bar, depending on drill model). This prevents costly oil leaks that reduce drill efficiency, cause component corrosion, and lead to unscheduled maintenance downtime.
We engineer the 0663214300 O-Ring to exact dimensional tolerances (compliant with ISO 3601 and AS568 standards), so it fits seamlessly into the hydraulic drill’s cylinder assemblies, valve connections, piston rods, and fluid transfer lines. Its primary function is to create a hermetic seal between mating components, blocking dust, dirt, and moisture from entering the hydraulic system—factors that majorly cause premature wear on pistons, bearings, and pump components. By maintaining a clean, pressure-stable hydraulic system, this O-Ring directly contributes to consistent drilling power, faster penetration rates, and extended service intervals for your hydraulic rock drill, reducing operational costs and maximizing equipment uptime.
This O-Ring works with leading hydraulic rock drill brands and models, including Atlas Copco ROC/D-series, Sandvik DX/TR-series, Boart Longyear LF-series, and Epiroc SmartROC drills—making it a versatile replacement part for both OEM specifications and aftermarket maintenance needs. For custom applications, we offer tailored solutions, including custom sizes, hardness ratings (60–90 Shore A), and material formulations to meet the specific demands of your drilling environment (e.g., high-temperature drilling in geothermal projects or chemical exposure in industrial mining).
Beyond its functional performance, we subject the 0663214300 O-Ring to rigorous quality control testing, including pressure cycle testing, temperature resistance validation, and dimensional accuracy checks, to ensure it meets or exceeds industry standards for reliability. We package each unit to prevent contamination during storage and shipping, with clear labeling of part number, material, and compatibility to streamline inventory management and on-site installation.
Whether you perform routine preventive maintenance, replace worn seals after heavy use, or source critical spare parts for emergency repairs, the 0663214300 Hydraulic Rock Drill O-Ring is a trusted choice for mining contractors, construction companies, and equipment maintenance teams. Our technical support team backs it with detailed installation guidelines and material selection advice to ensure optimal sealing performance and long-term durability, helping you keep your hydraulic rock drills operating at peak efficiency in the most demanding work sites.
