Hydraulic Fitting 41200002641 is a high-performance pipeline connection component exclusively engineered for Hydraulic Rock Drills. It thrives in extreme mining environments—including deep underground high-pressure hydraulic circuits, dust-intensive open-pit quarry drill pipelines, and semi-coastal mining sites with humid, corrosive air.
Mining operations pose unique challenges for hydraulic fittings: sustained high pressure (up to 48MPa) from drill hydraulic systems, frequent vibration (27G) caused by rock-breaking impact, hydraulic oil contamination with metal particles, dust accumulation in thread gaps, and extreme temperature swings. These issues often lead to fitting leakage, thread jamming, corrosion-induced failure, or joint loosening—resulting in costly hydraulic system downtime and reduced drilling efficiency. However, Hydraulic Fitting 41200002641 addresses these pain points head-on with tailored design and premium materials.
First, its 316L stainless steel body (superior to standard 316 steel) combined with a PTFE triple-seal ring delivers 48MPa high-pressure resistance and zero-leakage performance. This design prevents hydraulic oil waste and system pressure drop, boosting drill operational efficiency by 24% compared to double-seal fittings. Second, the precision-machined NPT thread (±0.009mm tolerance) features enhanced pitch accuracy and a self-locking structure, avoiding loosening from long-term vibration and dust buildup. Consequently, it reduces joint failure rates by 36% in daily mining use. Third, the 316L stainless steel material + nano anti-dust coating achieves 900-hour salt spray corrosion resistance, protecting against rust, hydraulic oil additives, and dust-induced abrasion—making it ideal for semi-coastal and dusty mining environments. This extends service life by 160% compared to ordinary hydraulic fittings.
Fourth, the vibration-dampening PTFE seal ring absorbs 27G vibration, maintaining seal integrity without deformation even during high-intensity drilling. This ensures reliable connections and eliminates sudden leakage risks. Fifth, the wide temperature adaptability (-40°C~125°C) guarantees stable performance in freezing high-altitude mines (-40°C) and hot underground hydraulic pipelines (125°C). Additionally, the nano anti-dust coating repels rock dust from thread gaps, preventing jamming during maintenance and reducing assembly/disassembly time by 20%.
Unlike generic industrial hydraulic fittings, this model is purpose-built for Hydraulic Rock Drills’ high-pressure, dust-prone, and vibration-intensive needs. The triple-seal design targets mining leakage risks, while the 316L stainless steel + anti-dust coating addresses corrosion and dust accumulation—features that align with real-world mining operational demands. As a result, it outperforms standard fittings in service life by 170%, significantly reducing maintenance downtime and costs.
Our manufacturing process includes precision CNC threading, nano anti-dust coating application, triple-seal assembly, and rigorous high-pressure testing. Each unit undergoes 48MPa pressure resistance testing, ±0.009mm thread precision verification, and 110,000-cycle vibration trials to ensure no leakage or performance degradation.
Notably, the fitting operates stably in temperatures ranging from -40°C (Arctic-grade mining regions) to 125°C (drill high-temperature hydraulic circuits). The 316L stainless steel body endures 7,000-hour hydraulic oil immersion tests with no corrosion, and the PTFE seal maintains flexibility and sealing performance for 16+ months in typical mining conditions.
The hydraulic fitting’s hexagonal wrench interface integrates seamlessly with mainstream Hydraulic Rock Drill high-pressure pipelines/hoses. It requires only standard tools for installation, simplifying on-site maintenance. Maintenance teams can complete replacement in just 10 minutes, minimizing operational downtime.
Our quality team conducts strict ISO 9001 verification for every unit, including high-pressure tests, leak inspections, corrosion resistance trials, and thread precision verification. Importantly, it complies with ISO 8434-3 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 95%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 60%.
It not only ensures tight, leak-proof connections for drill hydraulic pipelines but also extends the service life of drill hydraulic systems by 88%. Overall, Hydraulic Fitting 41200002641 delivers cost-effective, high-reliability performance for long-term mining operations. Beyond that, it minimizes downtime caused by fitting failure, maximizing operational efficiency and project profitability.
