Sealing technology of machines and devices is nowadays self-contained, dynamically developed technical specialization. It embodies seals tribology, materials science, designing and exploitation of the seals. Conference watchword "Tightness - criterion of the machines quality " is referred to protection of environment, to energy savings as well as to new approach of the seals design. Now, we design reliable and durable seals, we monitor leakage as well as the bolts tension in the flange connections. Conference organizers invite both seals manufacturers and users, scientists from technical universities and research centers and all these people interested with that specialization. Conference will be the forum of presentation of the latest achievements in the sealing technology and exchange of the technical conceptions.
