GKM back-up rings (metric)
The GKM series by Guarnitec offer a list of special profile static back-up rings designed for high-pressure performance. GKM seals are primarily designed for static applications where the seal remains stationary within a joint or assembly, although they can be used in dynamic sealing functions as well, offering reliable sealing over extended periods. They are characterized by their ability to maintain a seal even under high pressure conditions and are often chosen over O-rings in certain applications because they are less prone to disruptions caused by rolling.
GKM seals are produced in metric sizes.
