Page 1596 | 3.5 Controlling, Venting, Sealing of Liquids and Gases GN 7600 Sealing Rings Hygienic Design Information Specification 4 5 Components with cylindrical mounting surfaces which are installed in hygiene areas can be sealed and mounted without dead spaces using GN 7600 sealing rings. 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. • Hydrogenated acrylonitrile HNBR Butadiene rubber - - Blue - - Temperature resistant -25 °C to +150 °C - - FDA compliant - - Hardness 85 ±5 Shore A 85 • Ethylene propylene EPDM diene rubber - - Blue - - Temperature resistant -40 °C to +120 °C - - FDA compliant - - Hardness 85 ±5 Shore A 85 • Elastomer Characteristics → Page 2158 • RoHS 1 d 1 2 d 2 3 s 4 Material 5 Hardness How to order 1 2 3 4 5 GN7600-12-8-2-HNBR-85 1 2 3 d 1 d 2 d 3 d 1 d 2 d 3 d 4 s Nominal dimensions - Installation space Actual dimensions - Sealing rings, not mounted Suitable for 11  7 11,8 10,2 6,8 10,9 6,1 2 GN 1580 / GN 1581 12  8 12,8 11,2 7,8 11,9 7,1 2 GN 429 / GN 1580 13  9 13,8 12,2 8,8 12,9 8,1 2 GN 1581 14 10 14,8 13,2 9,8 13,9 9,1 2 GN 75.6 / GN 305 / GN 1580 16 12 16,8 15,1 11,7 15,8 11,0 2 GN 75.6 / GN 429 / GN 1581 18 14 18,8 17,0 13,6 17,7 12,9 2 GN 75.6 / GN 305 / GN 1580 / GN 5435 / GN 5445 19 15 19,8 17,9 14,5 18,6 13,8 2 GN 1581 21 17 21,8 19,9 16,4 20,5 15,7 2 GN 1580 / GN 5435 / GN 5445 22 18 22,8 20,8 17,4 21,4 16,7 2 GN 305 / GN 1581 / GN 8170 25 21 25,8 23,6 20,2 24,3 19,5 2 GN 20.1 / GN 1580 28 24 28,8 26,5 23,1 27,2 22,4 2 GN 20.1 / GN 1581 30 26 30,8 28,5 25,1 29,2 24,4 2 GN 20 32 28 32,8 30,4 27,0 31,1 26,3 2 GN 20 / GN 20.1 / GN 1580 34 30 34,8 32,3 28,9 34,0 28,2 2 - 36 32 36,8 34,2 30,8 34,8 30,1 2 GN 20.1
