Important: !!!!! Before you order: - Does your grill have a right-hand thread on the device? - Is this thread about 5/8" diameter? - Is your device a US model? Please order only if you can answer the above points with Yes. The original I&O BBQ conversion set for your USA grill: consisting of a DVGW approved (specially made) hose and a 30 mbar pressure regulator. Fits most US grills. So you can simply connect your USA grill to a German gas bottle. The hose has a 5/8 inch right-hand thread connection for your American grill and a 1/4 inch left-hand thread connection to connect it to the German pressure regulator. A 30 mbar regulator is included, as the grills from the USA are designed for a working pressure of 30 mbar. Your grill must have a connection with external thread on the grill, as a union nut is attached to the hose. There are some manufacturers such as Weber that have an internal thread. In this case, the set does not fit. Assembly takes approx. 20 minutes. No more filling the US bottles! Easy and legal conversion, no unsafe conversion, brand "Eigenbau", no shipping to packing stations
