Fluid Pneumatic Seals – Piston Seals

Fluid pneumatic seals, particularly piston seals, play a crucial role in the hydraulic industry by ensuring the proper functioning and longevity of hydraulic systems. Here's an overview:
What are Piston Seals?
Piston seals are components used to prevent the leakage of fluids in a hydraulic cylinder. These seals are also known us hydraulic seals. They are typically positioned in the piston head, which moves back and forth within the cylinder bore. Their primary function is to separate the two chambers inside the cylinder, maintaining the pressure differential needed for hydraulic movement
Types of Piston Seals
1. Single-Acting Piston Seals:
o  Used in applications where the pressure acts on one side of the piston.
o  Designed to seal in one direction only.
2. Double-Acting Piston Seals:
o  Used in applications where pressure can act on both sides of the piston.
o  Designed to seal in both directions.
Importance in Hydraulic Systems
• Leak Prevention: Piston seals prevent hydraulic fluid from leaking out of the cylinder, maintaining system efficiency and preventing contamination.
• Pressure Maintenance: By maintaining the pressure differential between the two sides of the piston, piston seals enable the hydraulic system to function correctly.
• Longevity: High-quality piston seals reduce wear and tear on other components, extending the life of the hydraulic system
