Hydraulic Fitting 41100019831 is a reliable medium-to-high pressure pipeline connection component exclusively designed for Hydraulic Rock Drills. It excels in harsh mining environments—for instance, underground medium-pressure hydraulic systems, drill pipeline junctions with frequent vibration, and inland mining sites with high humidity and dust.
These settings pose severe challenges for drill hydraulic fittings: continuous medium-to-high pressure (up to 42MPa), intense vibration (28G) from drill operation and rock impact, hydraulic oil erosion, dust accumulation, and temperature fluctuations. These issues often cause fitting leakage, thread wear, corrosion, or joint loosening, leading to drill hydraulic system pressure loss and costly downtime. Yet, Hydraulic Fitting 41100019831 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its high-strength alloy carbon steel body + NBR double-seal design achieves 42MPa pressure resistance and zero-leakage performance, preventing hydraulic oil waste and ensuring consistent system pressure. This improves hydraulic system stability by 22% compared to standard single-seal fittings. Second, the precision-machined BSPP thread (±0.01mm tolerance) features enhanced thread engagement, avoiding loosening caused by long-term vibration. Consequently, it reduces joint failure rates by 38% in daily mining operations. Third, the nickel-plated surface (20μm thickness) provides 800-hour salt spray corrosion resistance, protecting the fitting from rust and hydraulic oil additives—ideal for humid inland mining environments. Likewise, this extends service life by 150% compared to unplated carbon steel fittings.
Fourth, the vibration-absorbing NBR seal ring dampens 28G vibration from drill operation, maintaining seal integrity without deformation or displacement. Above all, this ensures reliable connection even during high-intensity drilling tasks, avoiding sudden leakage. Fifth, the wide temperature adaptability (-40°C~115°C) ensures stable performance in freezing high-altitude mines and hot underground drill hydraulic circuits. On top of that, the wear-resistant alloy steel body withstands repeated assembly/disassembly (≥40 times) without thread damage, facilitating on-site maintenance and reducing replacement costs.
Unlike ordinary industrial hydraulic fittings, this model is engineered for Hydraulic Rock Drills’ vibration-prone and medium-to-high pressure needs. To elaborate, the double-seal design targets mining leakage risks, while the nickel-plated surface addresses corrosion—features tailored to drill operational demands. Thus, it outperforms generic fittings in service life by 160%, significantly reducing maintenance downtime and costs.
Our manufacturing team uses precision CNC threading + nickel plating + double-seal assembly + pressure testing technology for the hydraulic fitting. Furthermore, each unit undergoes pressure resistance testing (42MPa) and thread precision verification (±0.01mm). Additionally, the fitting undergoes 100,000-cycle vibration trials to ensure no leakage.
Notably, it operates stably in temperatures from -40°C (Arctic mining regions) to 115°C (drill hydraulic pipelines). Moreover, the nickel-plated surface endures 6,000-hour hydraulic oil immersion tests with no peeling or corrosion. In addition, the NBR seal maintains flexibility and sealing performance for 15+ months in typical mining conditions.
The hydraulic fitting’s wrench-friendly hexagonal design integrates seamlessly with mainstream Hydraulic Rock Drill medium-to-high pressure pipelines/hoses. It requires only standard tools for installation, simplifying maintenance. As a result, maintenance teams can complete replacement in 9 minutes.
Our quality team conducts strict ISO 9001 verification for every unit. We perform pressure resistance tests, leak inspections, corrosion resistance trials and thread precision verification. Importantly, it complies with ISO 8434-2 international hydraulic fitting standards.
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 95%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 60%.
It not only ensures tight, leak-proof connection for drill hydraulic pipelines but also extends the service life of drill hydraulic systems by 85%. Overall, Hydraulic Fitting 41100019831 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it minimizes downtime caused by fitting failure, maximizing operational efficiency and project profitability.
