Gas line used in draft systems is typically made of what material?

In draft systems, the gas line is commonly made of braided vinyl or poly tubing due to its flexibility and resistance to various chemicals that may be present in gas systems. This type of material allows for ease of installation and maneuverability around tight spaces, which is important in systems where gas needs to be routed carefully.

Braided vinyl or poly tubing is also durable, helping to withstand the pressure and conditions commonly encountered in gas applications. Additionally, this type of tubing is designed to prevent potential leaks, which is crucial for safety in any setup involving gas.

While rubber tubing might be flexible as well, it may not offer the same level of durability and chemical resistance. Metal pipes are more rigid and often used in main gas lines but can be more difficult to install in tight or complex systems. Fiberglass is not typically used in gas lines, as it lacks the necessary properties to safely convey gas. This context emphasizes why braided vinyl or poly tubing is the standard for gas lines in draft systems.
