Hydraulic Seals in hydraulic applications plays a important function in hydraulic cylinder which convert fluid power into mechanical powers , are also known as JACKS or RAMS, they are used at high pressure and produce large forces and precise movement.
In pneumatic application hydraulic seals are used preventing leakage from gas/liquid as it is an expansive substance , its is dangerous to use at high pressure, as they limit to about 10 bar pressure, because gas / liquid is compressible substance , the motion of pneumatic cylinder is hard to control precisely .The basic theory for hydraulic & pneumatic cylinder is otherwise the same.
