ABSTRACT:
This invention relates to an adjustable packing for sealing a gap between two surfaces. The packing includes a packing member for sealing the gap, the sealing pressure thereof being adjusted by means of the elastomer, preferably two-component silicone, serving as a pressure medium. The elastomer is at least partially in the form of particles in an elastomer chamber. Between the elastomer and the walls of the elastomer chamber is preferably applied a suitable grease layer or a release agent layer which assists the function of the elastomer as a pressure medium.
