Hi . In our Jantar Standard ( 1977) plastic pipe for TEC probe inside vertical stabilizator is LEAKED . Is any solution to seal it ( for sample any liquid glue ) without opening stabilizator . Thanks .

Unfortunately, with plastic tubing that old, there is no point in heroics to try to plug one leak. The tubing is most likely old and rotten, and if you plug one leak, there will be another in some other spot in a few weeks or months. You are probably better off replacing the tubing. A Jantar service expert can probably do it with a minimum of hole-cutting.
