Hydraulic Fitting 40410027421 is a premium high-pressure pipeline connection component exclusively designed for Hydraulic Rock Drills. It excels in extreme mining environments—for instance, deep underground ultra-high-pressure hydraulic systems, high-impact tunneling drill pipelines, and coastal mines with severe salt spray corrosion.
These settings pose severe challenges for drill hydraulic fittings: extreme working pressure (up to 50MPa), intense shock (30G) from rock-breaking impact, aggressive hydraulic oil additives, salt spray/humid corrosion, and frequent pipeline vibration. These issues often cause fitting leakage, thread stripping, corrosion-induced rupture, or joint loosening, leading to drill hydraulic system failure and costly downtime. Yet, Hydraulic Fitting 40410027421 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its duplex stainless steel (2205) body + Viton triple-seal design achieves 50MPa ultra-high-pressure resistance and zero-leakage performance, exceeding industry standards by 15%. This eliminates hydraulic oil waste and system pressure drop, improving drill operational efficiency by 25% compared to standard fittings. Second, the precision-machined ACME thread (±0.008mm tolerance) features a self-locking structure, preventing loosening even under continuous 30G shock. Consequently, it reduces joint failure rates by 40% in long-term high-intensity use. Third, the duplex stainless steel (2205) material offers superior corrosion resistance, passing 1000-hour salt spray tests without rust or pitting—ideal for coastal or chemical-contaminated mining environments. Likewise, this extends service life by 180% compared to 316 stainless steel fittings.
Fourth, the shock-dampened Viton (FKM) seal ring absorbs 30G impact and vibration, maintaining seal integrity without deformation. Above all, this ensures reliable connection during extreme drilling tasks, avoiding sudden leakage risks. Fifth, the wide temperature adaptability (-45°C~130°C) ensures stable performance in freezing Arctic-grade mines and hot underground hydraulic circuits (up to 130°C). On top of that, the Viton seal withstands repeated assembly/disassembly (≥50 times) without performance degradation, simplifying maintenance and reducing replacement costs.
Unlike ordinary industrial hydraulic fittings, this model is engineered for Hydraulic Rock Drills’ ultra-high-pressure and shock-prone needs. To elaborate, the triple-seal design targets mining leakage risks, while duplex stainless steel addresses extreme corrosion—features tailored to drill operational demands. Thus, it outperforms generic fittings in service life by 190%, significantly reducing maintenance downtime.
Our manufacturing team uses precision CNC threading + triple-seal assembly + ultra-high-pressure testing technology for the hydraulic fitting. Furthermore, each unit undergoes pressure resistance testing (50MPa) and thread precision verification (±0.008mm). Additionally, the fitting undergoes 120,000-cycle shock vibration trials to ensure no leakage.
Notably, it operates stably in temperatures from -45°C (Arctic mining regions) to 130°C (drill high-temperature hydraulic pipelines). Moreover, the duplex stainless steel body endures 8,000-hour hydraulic oil immersion tests with no corrosion. In addition, the Viton seal maintains flexibility and sealing performance for 18+ months in typical mining conditions.
The hydraulic fitting’s thread-lock + O-ring dual-fixation design integrates seamlessly with mainstream Hydraulic Rock Drill high-pressure pipelines/hoses. It requires only standard wrenches for installation, simplifying maintenance. As a result, maintenance teams can complete replacement in 8 minutes.
Our quality team conducts strict ISO 9001 verification for every unit. We perform ultra-high-pressure tests, leak inspections, corrosion resistance trials and thread precision verification. Importantly, it complies with ISO 8434-1 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 ultra-tight, leak-proof connection for drill high-pressure pipelines but also extends the service life of drill hydraulic systems by 90%. Overall, Hydraulic Fitting 40410027421 delivers cost-effective, high-performance results for long-term mining operations. Beyond that, it minimizes downtime caused by fitting failure, maximizing operational efficiency and project profitability.
