The SLIPSIL sealing plug is easy to install. Compared to other mechanical sealing systems, the SLIPSIL plug is installed in no time. The plug parts, the outside of the tube and the inside of the passage opening are greased with SLIPSIL Vaseline. The plug parts are then simply pressed into the opening in a saw-tooth fashion. The fitting and tightening of bolts is unnecessary and the seal retains its functionality for decades.
