Knorr Pneumatic K-rings are reliable sealing rings used mainly in pneumatic systems where they prevent air leaks and protect impossible optimal operation. There are 2 different types of K-rings the Knorr KA seal and the Knorr KI seal. The difference here lies in whether these pneumatic seals are used in the piston or on the rod. Thanks to their low friction and high presence, K-rings are the ideal seal for long-term use under various pressure and temperature conditions.
