What is the difference between hydraulic and pneumatic applications?

Engineering and automation industries, generally rely on applications that are powered by either electric, hydraulic, or pneumatic systems.

Hydraulic and pneumatic applications are very similar in that they both channel mechanical energy using similar components. The main difference between the two is the medium used to transmit the force.

Hydraulics are pressurised liquids like oil, water, or synthetics. Whereas pneumatics operates by using easily compressible air or gases.

When it comes to maintaining the pressure of either liquids or gases, sealing plays an important role.

The difference between Hydraulic seals and Pneumatic seals

Hydraulic seals and pneumatic seals are the same in application but totally different in construction. Hydraulic seals are designed to work in a harsher environment and to withstand moveable forces. Whereas Pneumatic seals must be more flexible and have a less friction application due to operating at lower pressures.

Both hydraulic and pneumatic seals are used across a wide range of industries including but not limited to construction, plant, manufacturing, oil & gas, automotive, pharmaceutical, and food & beverage production.

FPE Seals stocks and manufactures a full range of sealing solutions and metal parts for both hydraulic and pneumatic applications. From piston seals, wiper seals, O-rings, and cylinder components.
