Introduction to Piston Seals
Piston seals are crucial components in hydraulic and pneumatic systems. They are designed to prevent the leakage of fluids (such as hydraulic oil in hydraulic cylinders) or gases (in pneumatic cylinders) between the piston and the cylinder wall. By creating a reliable seal, piston seals ensure the efficient transfer of pressure, which is essential for the proper functioning of various machinery and equipment. They play a vital role in maintaining the performance and reliability of hydraulic and pneumatic systems, which are widely used in industries such as construction, manufacturing, automotive, and aerospace.
