What Is a Flexible Gas Line?
A flexible gas line is an improvement over the traditionally-used iron pipes that were used to supply gas to homes for years. The key difference is in the material used, and it has been proven to be a safe and efficient alternative for installing residential gas lines. Advantages to using these flexible gas lines include less labor and the ability to add future gas lines.
Rather than heavy iron, flexible gas lines are made from corrugated stainless steel tubing (CSST). When used in homes, they supply natural gas to stoves, furnaces, gas fireplaces and many other appliances. They are permitted by all state and local building codes and have become more popular with builders in recent years.
Flexible gas lines made of CCST do not require the labor-intensive cutting and threading that iron pipes do. They are installed in much the same method as electrical lines, stretched between 2 connectors and cut to the needed length. These gas lines also do not need the large number of T-connections at 90 degrees every time they need to change directions. The CSST can simply be bent in any direction necessary. This flexibility has shown to reduce the frequency and number of gas leaks, making it a safer alternative to iron pipes.
