Parker piston seals for hydraulic and pneumatic cylinders and actuators are designed to separate applied pressure between the piston and the rod side during the stroke movement. They are available as single-acting and double acting seals in a wide range of compound and profile configurations to meet diverse applications: high and low temperatures and pressures, a wide variety of media, harsh operating conditions, various friction requirements, etc. Parker piston seals can cover working temperatures from -50°C to 230°C and working pressures up to 800 bar. Some seal profiles are insensitive to extreme pressure peaks. There are piston seals available that comply with ISO 6020, ISO 5597 and ISO 7425-1 standards.
