Serve to contain pressure on one side of a piston to prevent fluid from flowing across the cylinder head
Pneumatic piston seals
Operate in dynamic applications where seals and valves are actuated by air
Easy to assemble
Piston seals are often easy to install, even in closed housing
Best used with guiding elements
It is recommended for U-ring seals to be used with appropriate guide rings
Types of Piston Seals
