High-Pressure Perforator Seal for Hydraulic Rock Drills Engineered for extreme underground mining conditions, this perforator seal ensures leak-free sealing in high-frequency impact applications. Constructed from fluorocarbon rubber (FKM) with nitrile reinforcement, it withstands continuous pressures up to 300 bar while resisting chemical degradation from hydraulic fluids and mineral oils .
Technical Specifications & Design The seal features a 24 mm inner diameter (ISO 3601-1 tolerance) and M20 x 1.5 threaded ports for secure mounting . Its dual-layer design combines a rigid nitrile core with a flexible FKM outer layer, providing both structural stability and dynamic sealing performance. The surface finish (Ra ≤0.8 μm) minimizes friction during reciprocating motion, reducing wear on mating components .
Performance Advantages
Temperature Resistance: Operates reliably from -20°C to 200°C, making it suitable for both cold climates and high-heat drilling environments .
Durability: Nitrile reinforcement enhances resistance to abrasion and fatigue, extending service life by 30% compared to standard NBR seals .
Leak Prevention: The SAE J514-compliant threaded ports ensure leak-free connections even under cyclic pressure fluctuations .
