Hydraulic oil seals ROD PISTON SEALS PNEUMATIC SEALS
● 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.O-Ring-Loaded U-Cup Seals:Also known as loaded-lip seals and PolyPaks, an O-ring secures these U-cups to the rod or piston for better sealing performance at lower pressures than unsupported U-cup seals.Because U-cups have a sealing lip on both the inside and outside edges, they can be used for rod and piston sealing. Pistons require two seals—install one facing in each direction.
● Note: Maximum performance values cannot be achieved simultaneously;for example,speed is affected by pressure,temperature, and other operating conditions.
● These U-cup seals create less friction than O-ring-loaded U-cups, so they wear more slowly.
● Also known as lip seals,U-cups have a sealing lip on both the inside and outside edges,so they can be used for rod and piston sealing.Pistons require two seals—install one facing in each direction. U-cups that meet military specification AN6226 fit dimensions specified by the standard.
● Note:Maximum performance values cannot be achieved simultaneously;for example,speed is affected by pressure,temperature,and other operating conditions.
● PTFE gives these seals a slippery surface that allows rod speeds more than two times faster than our other piston seals.
● Note:Maximum performance values cannot be achieved simultaneously;for example,speed is affected by pressure,temperature,and other operating conditions.
