Types of Flexible Gas Lines

Flexible gas lines are used to carry natural gas or liquefied petroleum (LP gas or propane) from a gas main into a home, where the fuel powers appliances. Flexible lines may be used to connect buildings or to connect new appliances to an existing gas system. Different types of flexible gas lines are available for each gas supply project.

Available in coils of up to 1,000 feet or in shorter lengths as connectors with fittings in place, corrugated stainless steel tubing is a popular flexible gas line for indoor and outdoor applications. Stainless tubing is coated with polyethylene, polyvinyl chloride or epoxy to enhance durability.

Flexible copper tubing "snakes" through tight spaces and nontraditional pathways to supply gas appliances through home interiors. It can be bent up to 90 degrees, comes in lengths up to 100 feet and joins with standard fittings. Copper tubing has been used in homes for decades to transport water, air and natural gas.

Available in up to 500-foot lengths and iron and copper pipe size diameters, polyethylene (PE) gas pipe is used to bring natural gas or LP gas to a building. It is made of medium-to-high-density polyethylene, which is a noncorrosive, durable and relatively inexpensive plastic compound. PE gas line is used for exterior underground installation only.
