Hydraulic Fitting 41900002181 is an industrial-grade extreme-environment pipeline connection component exclusively engineered for Hydraulic Rock Drills. It excels in the most demanding mining scenarios—including deep underground ultra-high-pressure hydraulic circuits (≥1000m depth), high-impact tunneling drill pipelines, coastal mining sites with severe salt spray corrosion, and frigid high-altitude mining regions with sub-zero temperatures.
Mining operations in extreme environments pose unprecedented challenges for hydraulic fittings: sustained ultra-high pressure (up to 55MPa) from next-gen drill hydraulic systems, intense shock (35G) caused by hard rock-breaking impact, aggressive hydraulic oil with high additive concentrations, salt spray and mining slurry corrosion, heavy dust accumulation in thread gaps, and extreme temperature swings (-50°C~135°C). These issues often lead to catastrophic fitting failure—such as leakage, thread rupture, corrosion-induced breakdown, or joint loosening—resulting in costly downtime, reduced drilling efficiency, and potential safety hazards. However, Hydraulic Fitting 41900002181 addresses these critical pain points with cutting-edge design and premium materials.
First, its super duplex stainless steel 2507 body (superior to duplex 2205 and 316L) combined with a Perfluoroelastomer (FFKM) quintuple-seal ring delivers 55MPa extreme pressure resistance and zero-leakage performance—exceeding industry standards by 25%. This design eliminates hydraulic oil waste and system pressure drop, boosting drill operational efficiency by 30% compared to quad-seal fittings. Second, the precision-machined ACME thread (±0.007mm tolerance) features a self-locking structure and enhanced thread engagement, preventing loosening from long-term shock, vibration, and dust buildup. Consequently, it reduces joint failure rates by 45% in heavy-duty mining use. Third, the super duplex stainless steel 2507 material + DLC anti-wear coating achieves 1500-hour salt spray corrosion resistance—outperforming standard fittings by 50%—protecting against rust, hydraulic oil corrosion, and dust-induced abrasion. This makes it ideal for coastal, deep underground, and chemical-contaminated mining environments, extending service life by 200% compared to ordinary hydraulic fittings.
Fourth, the shock-dampening FFKM seal ring absorbs 35G vibration and impact, maintaining seal integrity without deformation even during high-intensity drilling in hard rock formations. This ensures reliable connections and eliminates sudden leakage risks in extreme impact scenarios. Fifth, the ultra-wide temperature adaptability (-50°C~135°C) guarantees stable performance in frigid high-altitude mines (-50°C) and hot underground hydraulic pipelines (135°C). Additionally, the DLC anti-wear coating repels rock dust and reduces friction during assembly/disassembly, preventing thread jamming and cutting maintenance time by 30%.
Unlike generic industrial hydraulic fittings, this model is purpose-built for Hydraulic Rock Drills’ extreme-environment needs. The quintuple-seal design targets ultra-high-pressure leakage risks, while super duplex steel 2507 + DLC coating addresses corrosion, wear, and dust accumulation—features that align with real-world mining operational demands. As a result, it outperforms standard fittings in service life by 200%, significantly reducing maintenance downtime and costs.
Our manufacturing process includes precision CNC threading, DLC coating application, quintuple-seal assembly, and rigorous extreme-pressure testing. Each unit undergoes 55MPa pressure resistance testing, ±0.007mm thread precision verification, and 150,000-cycle shock vibration trials to ensure no leakage or performance degradation.
Notably, the fitting operates stably in temperatures ranging from -50°C (Arctic-grade mining regions) to 135°C (drill high-temperature hydraulic circuits). The super duplex stainless steel 2507 body endures 10,000-hour hydraulic oil immersion tests with no corrosion, and the FFKM seal maintains flexibility and sealing performance for 24+ months in typical mining conditions.
The hydraulic fitting’s hexagonal wrench interface integrates seamlessly with mainstream Hydraulic Rock Drill ultra-high-pressure pipelines/hoses. It requires only standard tools for installation, simplifying on-site maintenance. Maintenance teams can complete replacement in just 8 minutes, minimizing operational downtime.
Our quality team conducts strict ISO 9001 verification for every unit, including extreme-pressure tests, leak inspections, corrosion resistance trials, and thread precision verification. Importantly, it complies with ISO 8434-5 international hydraulic fitting standards and mining safety certifications (e.g., ATEX, IECEx) for hazardous environments.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces hydraulic fitting-related failure rates by 97%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 70%.
It not only ensures tight, leak-proof connections for drill hydraulic pipelines but also extends the service life of drill hydraulic systems by 92%. Overall, Hydraulic Fitting 41900002181 delivers cost-effective, industrial-grade reliability for long-term extreme mining operations. Beyond that, it minimizes downtime caused by fitting failure, maximizing operational efficiency and project profitability.
