Lampa Scania Air Duster adapter to fit onto the Valve on the dashboard.
This has got to be the best version of this adapter I have ever tested.
Simply unscrew the core (middle bit) from the valve on the dashboard and screw this on.
You can then use the Lampa replacement hose and gun to have a quick disconnect Air duster gun for your cab!
No cutting hoses, no destructive fittings, and it doesn't come flying off every 10 minutes like the clip on type!
