Dusty Ring PT08023400 is a premium dust-proof sealing accessory exclusively designed for Hydraulic Rock Drills. It excels in extreme mining environments—for instance, high-temperature underground mines, wet drilling sites with water spray, and corrosive ore mining areas with chemical contaminants.
These settings pose severe challenges for drill dust rings: high-temperature operation (up to 150°C), water ingress during wet drilling, corrosive mine water, intense vibration (30G) from rock breaking, and heavy dust accumulation. These issues often cause dust ring hardening, cracking, water/dust leakage, or fiber delamination, leading to drill hydraulic component damage and costly downtime. Yet, Dusty Ring PT08023400 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its Fluororubber (FKM) base + aramid fiber reinforcement achieves IP67 dustproof/waterproof certification, blocking 100% of rock dust and preventing water intrusion (1m depth for 30 minutes). This eliminates hydraulic component contamination and extends drill service life by 160% compared to standard NBR dust rings. Second, the Shore A 75 hardness FKM balances elasticity and durability, ensuring tight contact with moving drill rods while resisting friction-induced wear. Consequently, it reduces seal replacement frequency by 35%. Third, the FKM material withstands continuous operation at ≤150°C, avoiding thermal hardening or cracking in high-temperature drill systems. Likewise, this ensures reliability in deep underground mining environments.
Fourth, the aramid fiber reinforcement enhances structural toughness, withstanding 30G vibration from drill operation without deformation or delamination. Above all, this prevents seal detachment and maintains consistent sealing performance during high-intensity drilling. Fifth, the FKM formulation resists corrosion from acidic mine water and hydraulic oil additives, complying with 600-hour chemical immersion test standards. On top of that, the precision-molded lip design optimizes dust scraping efficiency, removing 99.9% of dust from drill rod surfaces before it enters the cylinder.
Unlike ordinary industrial dust rings, this model is engineered for Hydraulic Rock Drills’ extreme working conditions. To elaborate, the FKM material targets high-temperature/corrosive environments, while aramid fiber reinforcement addresses mining vibration—features tailored to drill operational demands. Thus, it outperforms generic dust rings in service life by 170%, significantly reducing maintenance costs.
Our manufacturing team uses precision injection molding + aramid fiber braiding technology for the dusty ring. Furthermore, each unit undergoes IP67 dustproof/waterproof testing and hardness verification (Shore A 75). Additionally, the ring undergoes 120,000-cycle rod friction trials to ensure no performance degradation.
Notably, it operates stably in temperatures from -40°C (Arctic mining regions) to 150°C (drill high-temperature hydraulic cylinders). Moreover, it passes 500-hour salt spray tests with no corrosion or material degradation. In addition, the FKM surface endures 400-hour chemical immersion trials without swelling or cracking.
The dusty ring’s press-fit installation design integrates seamlessly with mainstream Hydraulic Rock Drill piston/rod assemblies. It requires no tools for installation or removal, simplifying maintenance. As a result, maintenance teams can complete replacement in 4 minutes.
Our quality team conducts strict ISO 9001 verification for every unit. We perform dustproof/waterproof tests, hardness inspections, vibration resistance trials and chemical resistance 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 dusty ring-related failure rates by 95%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 58%.
It not only ensures IP67 dustproof/waterproof sealing for drill components but also extends the service life of drill hydraulic cylinders/rods by 90%. Overall, Dusty Ring PT08023400 delivers cost-effective, high-performance protection for long-term mining operations. Beyond that, it minimizes downtime caused by seal failure, maximizing operational efficiency and project profitability.
