CNG tube is a component of compressed natural gas fuel system. It is a length of rigid fuel line widely used in natural gas powered vehicles (including mono-fuel, bi-fuel and dual-fuel vehicles). CNG tube is manufactured from galvanized low carbon steel tube properly annealed to ensure its flexibility so that the tube can be manually bent for easy installation. The outer surface of the steel tube is covered with a layer of PVC coating, which is achieved with proprietary technology so that the coating is evenly applied and tightly attached to the steel tube to offer sufficient protection. To guarantee the performance of CNG tube, it is tested in strict accordance with Part 16 of ISO 15500 Compressed Natural Gas (CNG) Fuel System Components – Rigid Fuel Line.
