Hydraulic & Pneumatic Seals

This page as PDF

Hydraulic seals and Pneumatic seals are a class of seals that are used in applications in either rotary or reciprocating motions. Hydraulic seals are exposed to hydraulic fluids such as hydrocarbon and phosphate ester and are designed for dynamic applications such as hydraulic cylinders. Hydraulic seals usually need to higher friction seals than pneumatic seals but often operate under lower operating speeds.

Pneumatic seals operate typically in air or other gaseous medium, with a minimum amount of lubrication. They are often used in peumatic cylinders and valves designed for lower operating pressure but typically demand higher operating speed and lower friction than hydraulic.

We offer a wide range of standard and custom sized seal for Pneumatic/Hydraulic cylinders.
