The O-Ring (Part No. 0663613401) is a precision-engineered sealing component we exclusively developed for Hydraulic Rock Drills—workhorse equipment in mining, quarrying, construction, and geotechnical drilling operations where reliable performance under extreme conditions is non-negotiable. We craft this O-Ring from high-grade nitrile butadiene rubber (NBR) or fluorocarbon rubber (FKM) (customizable based on client specifications for temperature and chemical resistance), and it outperforms standard sealing solutions in the harsh environments typical of rock drilling applications.
Hydraulic Rock Drills rely on consistent hydraulic pressure to power drill bits, advance rods, and operate auxiliary functions—making effective sealing critical to preventing fluid leakage, pressure loss, and contamination of sensitive internal components. We manufacture the 0663613401 O-Ring to tight tolerances (conforming to international standards such as ISO 3601) to ensure a perfect fit in drill hydraulic systems, including cylinders, piston assemblies, valve manifolds, pump housings, and hydraulic line connections. Its advanced elastomer formulation delivers exceptional resistance to hydraulic oils, mineral oils, synthetic lubricants, and even mild chemical contaminants, while also withstanding extreme temperatures ranging from -40°C to 200°C (depending on material grade) and pressure levels up to 3000 PSI—common stressors in deep rock drilling and hard-rock mining scenarios.
Beyond its material durability, we design the O-Ring with a precision-molded cross-section and smooth surface finish that minimizes friction against mating components, reducing wear on both the seal and adjacent parts (e.g., cylinder walls or valve seats) over time. This not only extends the service life of the O-Ring itself but also protects critical hydraulic system components from premature failure, directly lowering maintenance costs and unplanned downtime for mining and construction fleets. In addition, the seal’s resilience to compression set ensures it maintains its shape and sealing integrity even after prolonged use, eliminating the risk of slow leaks that can lead to reduced drill efficiency, increased fuel/fluid consumption, or costly damage to pumps and motors.
The 0663613401 O-Ring works with leading Hydraulic Rock Drill brands and models (including Atlas Copco, Sandvik, Boart Longyear, and Epiroc) as a direct replacement part that requires no modification to install—streamlining maintenance workflows for on-site technicians. We also rigorously test it for quality and performance, subjecting it to pressure cycling, temperature aging, and oil immersion tests to validate its reliability before it leaves the factory. Whether used for routine preventive maintenance, emergency repairs, or new drill assembly, this O-Ring ensures that Hydraulic Rock Drills maintain peak operational efficiency, even in the most demanding mining and construction sites where downtime can cost thousands of dollars per hour.
For operations prioritizing safety and productivity, the 0663613401 O-Ring is more than a spare part—it is a critical component that safeguards hydraulic system integrity, reduces environmental risk from fluid leaks, and supports uninterrupted drilling operations. Our technical support team backs it, and we offer a quality assurance guarantee, so this Hydraulic Rock Drill O-Ring delivers the durability, precision, and compatibility required to keep your drilling equipment running smoothly in the harshest working conditions.
