After years of territorial use of the bayonet filler, the cup filler and the Acme filler, the industry has finally come up with a common design to be used throughout Europe – eventually. Gradually, over the coming years, the Euro LPG filler will find its way into filling stations across Europe. This adapter has a 22mm thread for screwing into the center of the standard bayonet filler. Spain is the most recent country to join the LPG market and consequently the first to adopt this standard. Some Portuguese stations use this too.
