Hydraulic Fitting 41200029931 is a premium ultra-high-pressure pipeline connection component exclusively engineered for Hydraulic Rock Drills. It excels in the most demanding mining environments—including deep underground ultra-high-pressure hydraulic circuits, high-impact tunneling drill pipelines, and coastal mining sites with severe salt spray corrosion and frequent rock vibration.
Mining operations present unique challenges for hydraulic fittings: sustained ultra-high pressure (up to 52MPa) from advanced drill hydraulic systems, intense shock (32G) caused by rock-breaking impact, aggressive hydraulic oil additives, salt spray corrosion, dust accumulation in thread gaps, and extreme temperature swings. These issues often lead to fitting leakage, thread stripping, corrosion-induced rupture, or joint loosening—resulting in costly hydraulic system downtime, reduced drilling efficiency, and safety risks. However, Hydraulic Fitting 41200029931 addresses these pain points with industry-leading design and premium materials.
First, its duplex stainless steel 2205 body (superior to 316L and standard duplex steel) combined with a Viton quad-seal ring delivers 52MPa ultra-high-pressure resistance and zero-leakage performance—exceeding industry standards by 20%. This design prevents hydraulic oil waste and system pressure drop, boosting drill operational efficiency by 28% compared to triple-seal fittings. Second, the precision-machined ACME thread (±0.008mm tolerance) features a self-locking structure and enhanced thread engagement, avoiding loosening from long-term shock and dust buildup. Consequently, it reduces joint failure rates by 40% in heavy-duty mining use. Third, the duplex stainless steel 2205 material + ceramic anti-wear coating achieves 1200-hour salt spray corrosion resistance, protecting against rust, hydraulic oil corrosion, and dust-induced abrasion—making it ideal for coastal and deep underground mining environments. This extends service life by 180% compared to ordinary hydraulic fittings.
Fourth, the shock-dampening Viton seal ring absorbs 32G vibration and impact, maintaining seal integrity without deformation even during high-intensity drilling. This ensures reliable connections and eliminates sudden leakage risks in high-impact scenarios. Fifth, the wide temperature adaptability (-45°C~130°C) guarantees stable performance in freezing high-altitude mines (-45°C) and hot underground hydraulic pipelines (130°C). Additionally, the ceramic anti-wear coating repels rock dust from thread gaps, preventing jamming during maintenance and reducing assembly/disassembly time by 25%.
Unlike generic industrial hydraulic fittings, this model is purpose-built for Hydraulic Rock Drills’ ultra-high-pressure, shock-prone, and corrosion-intensive needs. The quad-seal design targets extreme leakage risks, while duplex stainless steel 2205 + ceramic coating addresses corrosion and wear—features that align with real-world mining operational demands. As a result, it outperforms standard fittings in service life by 190%, significantly reducing maintenance downtime and costs.
Our manufacturing process includes precision CNC threading, ceramic anti-wear coating application, quad-seal assembly, and rigorous ultra-high-pressure testing. Each unit undergoes 52MPa pressure resistance testing, ±0.008mm thread precision verification, and 120,000-cycle shock vibration trials to ensure no leakage or performance degradation.
Notably, the fitting operates stably in temperatures ranging from -45°C (Arctic-grade mining regions) to 130°C (drill high-temperature hydraulic circuits). The duplex stainless steel 2205 body endures 8,000-hour hydraulic oil immersion tests with no corrosion, and the Viton seal maintains flexibility and sealing performance for 18+ 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 9 minutes, minimizing operational downtime.
Our quality team conducts strict ISO 9001 verification for every unit, including ultra-high-pressure tests, leak inspections, corrosion resistance trials, and thread precision verification. Importantly, it complies with ISO 8434-4 international hydraulic fitting standards and mining safety certifications.
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 96%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 65%.
It not only ensures tight, leak-proof connections for drill hydraulic pipelines but also extends the service life of drill hydraulic systems by 90%. Overall, Hydraulic Fitting 41200029931 delivers cost-effective, industrial-grade reliability for long-term mining operations. Beyond that, it minimizes downtime caused by fitting failure, maximizing operational efficiency and project profitability.
