<p>The elastic seal is accommodated in a U-shaped supporting profiled section. It is elastic and pressed by gas or liquid pressure against the opposite surface. Under the elastic profiled seal inside the profiled section, is an elastic hose forcing it against the opposite surface when inflated. The ends of the channel-type profiled section can be bent inwards to enclose the sealing strip and hose.</p> |
