What Is a Hydraulic Seal?
A hydraulic seal is a critical component designed to contain fluids and prevent leaks in machinery and equipment, typically where oil is the working medium. It serves a dual purpose: it keeps fluids under high pressure contained within the system and prevents contamination by external particles. This dual functionality enhances machinery efficiency, ensures reliability, and reduces fluid waste.
Constructed from flexible materials like elastomers or plastics, hydraulic seals are essential in various machinery parts, including cylinders, valves, and pumps. They help maintain the necessary pressure differential within the system components, ensuring no internal fluid escapes. Common types of hydraulic seals include oil seals, O-rings, U-seals, and V-rings.
