Description

Hydraulic Seals are used to prevent leakage from the cylinders. Hydraulic Seals are able to withstand high pressures, extreme temperatures and transverse forces within the cylinder. The main function for Hydraulic Seals functions goes far beyond preventing fluid leakage.

Hydraulic cylinder seals are used to seal the opening between various components in the hydraulic cylinder. They are designed to retain hydraulic fluids, exclude solid or liquid contaminants, and maintain hydraulic pressure. These tasks require a variety of different seal designs and performance-enhancing features. Seal material must conform to irregularities in metal surfaces to block fluid passage. To adjust to clearance gap size changes, the seal must expand or compress rapidly to follow dimensional variations. Finally, to resist being extruded into gaps, the seal must have sufficient modulus and hardness to withstand shear stress produced by system pressure.
