High-Pressure Metal-Wound Graphite Gasket Engineered for extreme underground mining conditions, this gasket ensures leak-free sealing in high-frequency impact applications. Constructed from SUS304 stainless steel with a graphite filler layer, it withstands continuous pressures up to 250 bar while resisting chemical degradation from hydraulic fluids and mineral oils.
Technical Specifications & Design The gasket features a 24 mm inner diameter (ISO 3601-1 tolerance) and M24 x 1.5 threaded ports for secure mounting. Its spiral-wound design combines a rigid stainless steel core with a flexible graphite layer, providing both structural stability and dynamic sealing performance. The surface finish (Ra ≤0.8 μm) minimizes friction during installation, reducing wear on mating components.
Performance Advantages
Temperature Resistance: Operates reliably from -196°C to +870°C, making it suitable for both cryogenic and high-heat drilling environments.
Durability: Graphite filler enhances resistance to abrasion and fatigue, extending service life by 40% compared to standard rubber gaskets.
Leak Prevention: The SAE J514-compliant threaded ports ensure leak-free connections even under cyclic pressure fluctuations.
Applications
Underground Mining: Essential for hydraulic rock drills in tunnel boring and ore extraction, where consistent pressure retention is critical.
Heavy Machinery: Used in excavators and loaders to seal hydraulic cylinders during high-impact operations.
Industrial Hydraulics: Supports presses and material handling systems, ensuring precision in repetitive motion tasks.
