hydraulic SEALS

REtain hydraulic fluids and pressures

Hydraulic sealing systems for earth moving/construction machinery, agriculture machinery, agricultural/forestry machinery, material handling, industrial hydraulics, vehicle engineering and mining.
The main tasks of hydraulic seals are to retain hydraulic fluids, exclude solid or liquid contaminants and to maintain hydraulic pressure.  These tasks require different seal designs and accessories.  

Key types of hydraulic seals include:

Wiper Seals
Wiper seals, also know as Scraper seals, create a tight fit which allows a
reciprocating ram rod to pass through the inner bore of the seal. 
They are used to eliminate contaminants such as dirt, moisture and dust. 

Rod Seals
Rod seals prevent leakage of fluid from with in 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 is 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.
