Piston Seals

Hydraulic Piston Seals

The primary function of hydraulic piston seals is to effectively seal the fluid on the piston side, preventing leakage to the opposite side of the cylinder. They also help to maintain the hydraulic pressure and ensure efficient operation of the system.

Piston seals are usually made from materials such as elastomers or thermoplastics, which offer good sealing properties and resistance to hydraulic fluids. They are designed to withstand high pressures and temperature variations commonly encountered in hydraulic systems.

Designs and Applications

Hydraulic piston seals come in various designs, including single-acting and double-acting seals:

• Single-acting seals: Provide sealing in one direction, typically used in applications where the fluid pressure acts on one side of the piston.
• Double-acting seals: Provide sealing in both directions, suitable for applications where the fluid pressure acts on both sides of the piston.

The design of hydraulic piston seals may vary depending on the specific application and operating conditions. Some common types of piston seals include:

• Lip seals
• V-packings
• Composite seals

Each design has its advantages and is selected based on factors such as pressure, temperature, fluid compatibility, and the required level of sealing performance.
