Solution to a sealing problem

Dichtomatik, can provide Kalrez perfluoroelastomer 'O' rings from the Dupont Performance Polymers range. DuPont Kalrez Spectrum 7090 seals, for example, are aimed at applications needing high hardness/higher modulus
DuPont Kalrez Spectrum 7090 seals, for example, are aimed at applications needing high hardness/higher modulus properties. They have extensive mechanical properties including compression set resistance and seal force retention with good responses to temperature cycling effects and RGD resistance. They are well suited to combined static and dynamic sealing, especially where high temperatures or extrusion resistance are involved. A working temperature of 325Â°C is possible, with short excursions at a higher temperature acceptable.
A recent installation was for a trunnian mounted ball valve used in gas cleaning/ sweetening processes.
