The O-Ring (Part Number: 0663212800) is a mission-critical sealing component engineered exclusively for Hydraulic Rock Drills—indispensable equipment in mining, quarrying, construction, and geotechnical drilling projects where reliable performance under extreme conditions is non-negotiable. We craft this O-Ring from high-grade nitrile rubber (NBR) or fluorocarbon rubber (FKM) (customizable to match your hydraulic fluid type and operating temperature), so it can withstand the harshest operating environments of hydraulic rock drills: sustained high pressure (up to 350 bar, depending on drill model), constant mechanical vibration, exposure to mineral oils, hydraulic fluids, abrasive dust, and temperature fluctuations ranging from -40°C to 120°C.
Unlike generic O-Rings that fail prematurely in rock drill applications, we precision-mold the 0663212800 to tight dimensional tolerances (compliant with ISO 3601 standards) to ensure a perfect, interference-free fit with critical hydraulic system components—including drill cylinders, piston assemblies, valve bodies, hydraulic line connections, and rotary drive mechanisms. This exacting fit eliminates micro-leakages that not only waste costly hydraulic fluid but also introduce air into the system, leading to pressure drops, erratic drill performance, and accelerated wear of pistons, seals, and other high-value components. By maintaining a hermetic seal, the 0663212800 O-Ring preserves optimal hydraulic pressure, ensuring consistent hammer impact force, smooth feed movement, and reliable rotation—key to maximizing drilling speed, accuracy, and overall productivity in rock formation penetration.
Beyond its sealing function, this O-Ring acts as a protective barrier against dust, rock chips, and environmental contaminants that infiltrate drill assemblies during operation. In mining and quarrying sites, where airborne silica dust and abrasive particles are pervasive, unprotected hydraulic components face rapid corrosion and abrasion; the 0663212800’s robust rubber composition and tight seal block these contaminants, extending the service life of hydraulic pumps, motors, and valves by up to 50% compared to standard replacement seals. This translates to fewer unplanned maintenance stops, reduced downtime, and lower long-term equipment ownership costs for drill operators.
Leading Hydraulic Rock Drill manufacturers (including Atlas Copco, Sandvik, Boart Longyear, and Furukawa) design their models to work with the 0663212800 O-Ring, making it a direct drop-in replacement for OEM parts that requires no modifications to drill assemblies. Its user-friendly design enables quick installation—even in remote job sites—with basic hand tools, minimizing service time and getting your drills back to work faster. We subject each unit to rigorous quality control testing, including dimensional verification, hardness testing (Shore A 70-90, tailored to application), tensile strength assessment, and compression set resistance trials, to ensure it meets or exceeds OEM performance specifications.
For routine preventive maintenance, emergency seal replacement, or new drill assembly, mining contractors, construction firms, and drill maintenance teams trust the 0663212800 O-Ring. Whether you operate surface rock drills in open-pit mines, underground jumbo drills in tunneling projects, or handheld hydraulic drills for foundation work, this O-Ring delivers uncompromising sealing performance to keep your hydraulic rock drills running at peak efficiency. We back it with a 12-month warranty against manufacturing defects and a dedicated technical support team to assist with installation guidance or compatibility verification—making the 0663212800 O-Ring more than a replacement part, but an investment in the reliability and profitability of your drilling operations.
We also offer bulk packaging options for fleet maintenance programs, as well as custom coating solutions (e.g., PTFE coating for enhanced wear resistance) for extreme-duty applications such as hard rock drilling or high-temperature underground mines. Our inventory is stocked to ensure fast global shipping, with same-day dispatch for urgent orders, so you never face costly delays due to seal shortages.
