Made of aluminum alloy with fine workmanship, strong, durable for long time use. This product can be used together with 4 outdoor cassette gas tanks for gas supply. It is generally used in products with large gas consumption to ensure that the gas tanks are not changed during long-term use. Or when a product is in use, a gas tank is not enough gas, but it cannot be turned off to replace the gas tank in the middle. In use, the gas between the gas tanks will not circulate with each other, and the gas with high pressure will not flow to the low pressure, so as to ensure the safety of use. 4 gas tanks can be connected to the product, which can be used with 2 or 3 gas tanks, and the gas will not leak if the other is not connected. The threaded interface is 7/16-28 teeth, and is used for outdoor cassette gas tanks.
