Clog 4041000795 is a critical sealing/protective accessory exclusively designed for Hydraulic Rock Drills. It excels in harsh mining environments—for instance, underground hard rock mines, high-altitude quarries, tunnel construction sites and oil-contaminated drilling areas.
These settings pose unique challenges for drill clogs: hydraulic oil erosion, abrasive rock dust, intense vibration (up to 25G), temperature swings, and water ingress. These issues often cause clog cracking, wear, leakage, or corrosion, leading to drill hydraulic system contamination and costly downtime. Yet, Clog 4041000795 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its nitrile rubber (NBR) outer layer + reinforced nylon core delivers excellent oil resistance (compliant with ISO 696), resisting erosion from hydraulic oil and lubricants. This eliminates clog swelling or cracking, extending service life by 140% compared to standard rubber clogs. Second, the Shore A 75 hardness rubber surface withstands abrasion from rock dust and mechanical friction. Consequently, it avoids premature wear and maintains a tight seal, reducing system contamination risks by 30%. Third, the anti-corrosion nylon core resists rust and chemical erosion from mining slurry. Likewise, this ensures structural integrity even in humid underground environments.
Fourth, the vibration-resistant design (flexible rubber + rigid core combination) withstands 25G vibration from drill operation. Above all, this prevents clog loosening and leakage, ensuring continuous protection for hydraulic system ports. Fifth, the wide temperature adaptability (-40°C~120°C) ensures reliable performance in freezing high-altitude mines and hot underground drilling sites. On top of that, the precision-molded shape matches drill port dimensions, providing a leak-proof seal without modification.
Unlike ordinary industrial clogs, this model is engineered for Hydraulic Rock Drills’ dynamic working conditions. To elaborate, the NBR rubber adapts to drill hydraulic oil exposure, while the reinforced core matches vibration characteristics. Thus, it outperforms generic clogs in service life by 150%, significantly reducing replacement-related downtime.
Our manufacturing team uses precision injection molding + vulcanization technology for the clog body. Furthermore, each unit undergoes oil resistance testing (ISO 696) and hardness verification (Shore A 75). Additionally, the clog undergoes 100,000-cycle vibration trials to ensure no loosening or leakage.
Notably, it operates stably in temperatures from -40°C (high-altitude cold regions) to 120°C (drill hydraulic systems). Moreover, it passes 500-hour oil immersion tests with no swelling or performance loss. In addition, the NBR rubber endures 300-hour abrasion trials without excessive wear.
The clog’s press-fit installation design integrates seamlessly with mainstream Hydraulic Rock Drill hydraulic ports. It requires no tools for installation or removal, simplifying maintenance. As a result, maintenance teams can complete replacement in 5 minutes.
Our quality team conducts strict ISO 9001 verification for every unit. We perform oil resistance tests, hardness inspections, vibration resistance trials and leak verification. Importantly, it complies with ISO 3601 international hydraulic seal standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces clog-related failure rates by 93%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 55%.
It not only ensures leak-proof sealing for drill hydraulic ports but also extends the service life of drill hydraulic systems by 85%. Overall, Clog 4041000795 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it minimizes downtime caused by clog failure, maximizing operational efficiency and project profitability.
