The inside of natural gas hose is made of high-quality 304 stainless steel bellows, and the outside is surrounded by a rubber tube to prevent gas leakage. Each gas tube has undergone three-layer pressure testing, which is durable, reliable in quality and can extend its service life. There are solid brass connector interfaces at both ends, which have very good weather resistance.

Gas tubing pipe kit is easy to install, can be cut and bent at will, while the inner warp flow remains unchanged, and it can be bent and passed freely in a narrow space. There is no interface in the middle of the pipe body, reducing the connection point to prevent gas leakage and increasing safety.
