Round VW Puck Adapter
This adapter is primarily for Volkswagen applications (e.g. JF56E & 09M) but can be used for some Jaguar, Land Rover, and Mazda as well.
**These are the applications that we KNOW this adapter fits. There may be more. If the adapter you are attempting to use fits securely and tightly without any leaks, then feel free to use that fitting.
