Rod Seal Types
Piston rod seals are essential in hydraulic and pneumatic systems, designed to prevent fluid leakage and maintain pressure. There are several types of piston rod seals, each tailored for specific applications:
U-Cup Seals: These versatile seals offer excellent sealing performance and low friction. They are typically made from polyurethane or rubber and are suitable for a wide range of pressures and temperatures.
Lip Seals: Featuring one or more sealing lips, these seals provide a tight seal against the rod. They are effective in high-pressure applications and are often made from materials like PTFE or nitrile rubber.
V-Ring Seals: Comprising multiple V-shaped rings stacked together, these seals offer robust sealing capabilities, especially in high-pressure and dynamic environments.
Buffer Seals: Used alongside primary rod seals, buffer seals absorb pressure spikes and protect the primary seal from excessive wear, enhancing the overall system’s durability.
Compact Seals: These multi-component seals combine different materials and designs to offer enhanced sealing performance and longevity, making them ideal for demanding applications.
Each type is selected based on factors such as pressure, temperature, and the type of fluid in the system, ensuring optimal performance and reliability.
