Worked great for my 1993 VW Corrado.This is the type of ports that VW used in 90s, stupid design with non replaceable core, when it leaks you have to replace whole port. This product here is a great value for money compared to other sources, is a direct replacement. I tested it with bubble soap after installation and it does not leak. Was able to pull 200 micron vacuum on the system.This is the type of ports that VW used in 90s, stupid design with non replaceable core, when it leaks you have to replace whole port.

Make sure you're using backup wrench on the line so you don't break the line.
