Flexible Gas Connectors

Please inspect and replace any deteriorated, older-style brass, flexible gas connectors in your home. Gas connectors are corrugated metal tubes used to connect gas appliances, such as dryers, stoves or water heaters, to gas supply lines. Currently these connectors are made of stainless steel or plastic coated brass. In the past, these connectors were made of uncoated brass. These older brass connectors may have a flaw in how the tubing was joined to the end pieces. These older brass connectors have end pieces brazed (soldered) to corrugated brass tubing. Over time, the brazing can fail, creating a serious gas leak. These dangerous, uncoated brass connectors have not been made for more than 20 years, but many of them are still in use. It is difficult to determine from a visual inspection weather a flexible connector has been brazed. Therefore, if an uncoated brass connector is found, it should be replaced with either a new stainless steel or plastic coated brass connector. It is a good practice to replace any flexible gas connector that is more than 10 years old.

Furthermore, connectors can wear out from too much moving, bending, or corrosion. Connectors should always be replaced whenever the appliance is replaced or moved from its location. Any new flexible gas connector should be certified by the American Gas Association (AGA) and conform to the rules of the American National Standards Institute (ANSI) Standard Z21.24. When you purchase a new flexible gas connector, make sure that it has an AGA or ANSI approval label attached.

If you smell gas or suspect a leak:

  1. Leave the building immediately.
  2. Do not use your phone. Call the fire department and your gas company from a neighbors phone.
  3. Do not light a match or lighter.
  4. Do not change the position of any light switch. Do not switch on any electrical appliances or equipment.
