Flexible Gas Connectors

Flexible gas connectors are corrugated metal tubes used to attach natural gas appliances to a home or building's natural gas supply pipes. Some older, uncoated brass flexible gas connectors can corrode or break and cause a serious gas leak, fire or explosion.

According to the U.S. Consumer Product Safety Commission, these uncoated brass flexible gas connectors have not been made for more than 25 years, but many are still in use. If you have a natural gas appliance that is more than 20 years old, it is a good idea to have the gas connectors replaced.

WARNING: Moving an appliance to check the gas connector may cause the connector to break, resulting in a gas leak, fire or explosion. DO NOT attempt to check the connectors yourself. Instead, have a qualified person, such as a professional plumber or HVAC or appliance repair contractor, inspect your appliances and, if necessary, replace the connectors for you. The new connector should be certified by the American Gas Association and be manufactured in conformance with the American National Standards Institute. Duke Energy also reminds you that you should have all of your natural gas appliances inspected in accordance with the manufacturer's recommendations.

If you suspect a natral gas leak in your home or building:

  • For your safety, we recommend that you and anyone else in the home or building leave the premises immediately.
  • From a neighbor's home or other safe location, call 911 and Duke Energy at 1-800-634-4300.
  • Do not start any vehicle if it is in an attached garage.
  • Do not operate an automatic garage door.
  • Do not use matches, open flames, lighters or cigarettes in the home or building.
  • Do not turn on or off electrical switches or appliances.
  • Do not use phones (including cellular phones) inside the home or building.
  • Do not re-enter the home or building until cleared to do so by a Duke Energy representative.
  • Watch for the Duke Energy truck to arrive and meet the representative at or near their vehicle.
