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 charge pump• Able to withstand wear over time.Applications: An O-ring seal is Installed in a groove in the pump housing where it seals against a rotating shaft and other moving parts to ensure that the hydraulic fluid remains contained within the pump, allowing for efficient and reliable operation of the equipment's hydraulic functions.
