Additional standard materials available. Maximum operating temperature in air is 50°F ( 28°C) below specified max. temperature.
Important Note: Maximum values above depend on extrusion gap, clearances, seal material, media, temperatures, pressures, surface speed, dynamic running surface finish and working environment. Seals cannot be operated at their upper ratings at the same time. For pressure above specified operating pressure or for any advice, please contact engineering@ahpseals.com
