All standard parts equipped and delivered with sealing rings GN 7600 are listed in the table. For replacement, the corre- sponding sealing rings can be ordered individually. As delivered, or unassembled, the sealing rings have the “actual dimensi- ons” as stated in the table. To ensure a firm seating and reliable sealing, a corresponding installation space must be provided in the component. This ensures that when the sealing ring is installed, it will be subject to the necessary pressure without excess load. All surfaces which are in contact with the sealing ring should have a minimum surface quality of Ra 0.8 μm.
