The Concave Cup Gasket is a high-precision, metal-stamped sealing component engineered to deliver reliable fastening, excellent sealing performance, and long-term operational stability in demanding mechanical environments. With its unique concave, cup-shaped profile, the gasket effectively distributes load forces, minimizes vibration, and prevents loosening or leakage even under continuous pressure or fluctuating mechanical stress.
To ensure optimal performance, the gasket is manufactured from premium-grade materials, including stainless steel, carbon steel, brass, aluminum, or customized alloys. These materials provide superior corrosion resistance, mechanical strength, and fatigue resistance, making the gasket suitable for prolonged use in harsh conditions such as humidity, oil contact, temperature variation, or chemical exposure.
Every gasket undergoes precise stamping or deep-drawing processes, resulting in accurate dimensions, smooth edges, and a consistent surface finish. This precision not only enhances sealing capability but also ensures easy installation with screws, bolts, threaded rods, rivets, or automated assembly systems. Customized options—such as material thickness, inner/outer diameter, hardness level, and surface coating—are available to meet specific engineering requirements or OEM/ODM needs.
Widely utilized across multiple industries, the concave cup gasket serves as a reliable solution in automotive and motorcycle components, hydraulic and pneumatic equipment, household appliances, electrical connectors, power devices, and high-precision industrial machinery. In these applications, it functions as a seal, spacer, shock absorber, protective barrier, or load-bearing component, ensuring structural integrity and high sealing efficiency.
