This product can decompose 1 outdoor gas tank into 2 interfaces, so that 2 products can be used at the sametime, such as cooking, heating, and lighting, or 2 lightings can be used directly. During use, the gases between the gas tanks will not flow to each other, and the gases with high pressure will not flow to the ones with low pressure, ensuring safe use. The threaded interface is 7/16-28 threads, and can be used for outdoor 110g, 230g, and 450g gas tanks. The cassette tank can also be connected and used through the cassette adapter conversion, and it can also be used for MAPP tanks through the adapter.
