Hydraulic Fitting 419000011471 is an industrial-grade extreme-duty component for Hydraulic Rock Drills. It excels in the most demanding mining scenarios. For instance, it performs in deep underground circuits (≥1200m depth) and high-impact hard rock tunneling sites. Additionally, it thrives in coastal salt spray areas and frigid high-altitude mines.
Extreme mining environments pose unique challenges for hydraulic fittings. First, ultra-high pressure (up to 55MPa) strains connections from next-gen drill systems. Second, 35G shock hits fittings during hard rock-breaking impact. Third, aggressive hydraulic oil with high additives causes corrosion. Fourth, salt spray and mining slurry wear down surfaces. Fifth, dust clogs thread gaps, and temperature swings (-50°C~135°C) test durability.
These issues often lead to catastrophic failure. For example, leakage, thread rupture, corrosion breakdown or joint loosening are common. As a result, costly downtime, reduced efficiency and safety hazards occur. Yet, Hydraulic Fitting 419000011471 solves these pain points with advanced design.
First, its super duplex steel 2507 body outperforms duplex 2205 and 316L. Moreover, the FFKM enhanced quintuple-seal ring delivers 55MPa pressure resistance. It achieves zero-leakage performance, exceeding industry standards by 25%. This eliminates oil waste and pressure drop. Consequently, it boosts drill operational efficiency by 30% vs. quad-seal fittings.
Second, precision-machined ACME thread has ±0.007mm tolerance. Notably, it features a self-locking structure and enhanced engagement. This prevents loosening from shock, vibration and dust. As a result, joint failure rates drop by 45% in heavy-duty use.
Third, super duplex steel 2507 + DLC coating offers 1500-hour salt spray resistance. This outperforms standard fittings by 50%. Furthermore, it protects against rust, oil corrosion and dust abrasion. It is ideal for coastal, deep underground and chemical-contaminated sites. Likewise, service life extends by 200% vs. ordinary fittings.
Fourth, the FFKM seal ring absorbs 35G shock and vibration. Importantly, it maintains integrity without deformation during high-intensity drilling. This eliminates sudden leakage risks in extreme impact scenarios.
Fifth, the -50°C~135°C temperature range ensures stable performance. It works in freezing high-altitude mines and hot underground pipelines. On top of that, the DLC coating repels rock dust and reduces friction. This prevents thread jamming and cuts maintenance time by 30%.
Unlike generic industrial fittings, this model is purpose-built for drills. Specifically, the enhanced quintuple-seal targets ultra-high-pressure leakage. Additionally, super duplex steel 2507 + DLC coating addresses corrosion, wear and dust. These features align with real mining demands. As a result, it outperforms standard fittings by 200% in service life. This significantly reduces maintenance downtime and costs.
Our manufacturing process uses precision CNC threading and DLC coating. Furthermore, it includes enhanced quintuple-seal assembly and extreme-pressure testing. Each unit undergoes 55MPa pressure tests and ±0.007mm thread verification. It also passes 150,000-cycle shock vibration trials. Notably, no leakage or performance degradation is allowed.
The fitting operates stably from -50°C to 135°C. Moreover, the super duplex steel body endures 10,000-hour oil immersion tests. No corrosion occurs during this period. Additionally, the FFKM seal maintains flexibility for 24+ months in typical mining conditions.
The hexagonal wrench interface integrates seamlessly with drill pipelines. It requires only standard tools for installation. Consequently, maintenance teams complete replacement in just 8 minutes. This minimizes operational downtime.
Our quality team conducts strict ISO 9001 verification. For example, tests include extreme-pressure checks, leak inspections and corrosion trials. Thread precision is also verified. Importantly, the fitting complies with ISO 8434-5 standards. It also holds mining safety certifications (ATEX, IECEx) for hazardous environments.
It is a direct OEM replacement for top Hydraulic Rock Drill brands. Furthermore, its reliability reduces fitting-related failure rates by 97%. Backed by a 12-month warranty, it cuts annual maintenance costs by 70%.
It ensures tight, leak-proof connections for drill hydraulic pipelines. Additionally, it extends the service life of drill hydraulic systems by 92%. Overall, it delivers cost-effective, industrial-grade reliability. It minimizes downtime from fitting failure. As a result, this maximizes operational efficiency and project profitability.
