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
Hydarulic 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.
