The main tasks of hydraulic seals are to retain hydraulic fluids, exclude solid or liquid contaminants and maintain hydraulic pressure. These tasks require different seal designs and accessories.

Key types of hydraulic seals include:


Wiper Seals Wiper seals, also known as scraper seals, create a tight fit which allows a reciprocating ram-rod to pass through the inner bore of the seal. These are used to eliminate contaminants such as dirt, moisture and dust.	Rod Seals Rod seals prevent leakage of fluid from within the cylinder to the outside as the rod is in motion. Rod seals work together with the wiper seals to protect the hydraulic system against external contamination due to dirt and weather conditions.

Wear Seals Wear seals are used to help keep the piston centered, allowing even wear and pressure distribution on the seals. They can be used in both piston and rod applications.	Piston Seals Hydraulic Piston Seals are designed to ensure fluid and other media does not penetrate the piston as the system pressure pushes the piston down the cylinder during pressure cycle.
