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.

Flange seals provide the front-face static sealing function within flange connections. There are two major design principles available, either for internal or external pressure. Various designs in a broad range of compounds provide individual features. Parker’s flange seals offer enhanced sealing performance from pressure-free to high-pressure conditions. Designs can be optimized to be insensitive to pressure peaks, show high extrusion resistance or media resistance.
