An O-ring seal is a circular elastomeric gasket with a torus-shaped cross-section. It is used in mechanical assemblies to prevent the escape of gases and fluids under compression. The design ensures a tight seal between mating surfaces, even when there are slight imperfections, by deforming slightly to fill gaps and irregularities. The primary function of an O-ring seal is to prevent the leakage of fluids or gases between two mating surfaces. When compressed between two parts, the O-ring forms a seal that withstands pressure differentials and prevents contaminants from entering or escaping the system.Attributes:• Provides flexibility and resilience.• Withstands the pressures of the solenoid valve.• Able to withstand wear over time.Applications: An O-Ring Seal is situated within the solenoid valve cartridge where it forms a seal between the valve's moving components and the stationary housing. This ensures that hydraulic fluids are properly controlled and contained within the system, contributing to the overall reliability and efficiency of the solenoid valve.
