Appliance connectors are corrugated metal tubes used to connect gas appliances to fuel gas supply pipes. Some older brass connectors have a serious flaw in how their tubing was joined to their end pieces. These older brass connectors have not been in production for more than 20 years now, but might still be found and in use in older homes and buildings.
Over time, the end pieces can separate from the tubing and cause a serious natural gas leak, explosion or fire. Uncoated brass connectors should be replaced immediately. Although not all uncoated connectors have this flaw, it is very difficult to tell which ones do. Therefore, any uncoated brass connectors should be replaced immediately with a new plastic-coated brass connector or a new stainless steel connector.
Only a qualified professional should check or replace connectors. Do not move your appliance to check the connector! They can easily break if moved even slightly. For your safety, make sure a qualified professional performs the inspection and immediately replaces any uncoated brass connectors with stainless steel or plastic-coated connectors.
Each appliance should have a shut-off valve installed on the house piping before the connector. Connectors should:
Tubing has broken off the end piece.
Tubing has corroded, causing a hole.
No visible defect, although all uncoated brass connectors need to be replaced.
Uncoated, stainless steel connector.
Coated stainless steel connector.
Coated stainless steel connector.
Dryer with uncoated brass connector - unacceptable
Stove with uncoated brass connector - unacceptable
Dryer with coated stainless steel connector - acceptable
Stove with uncoated stainless steel connector - acceptable
Gas appliance connectors are corrugated metal tubes used to connect your home's gas appliances to fuel gas supply pipes.
There are three types of acceptable appliance connectors:
Unacceptable, dangerous connectors are those that are uncoated brass.
Your dryer, stove, range and cook top probably have flexible connectors if they use natural gas. It is recommended that your water heater and furnace have solid piping.
If your appliance is more than 20 years old, there is a good chance that it may have an uncoated brass connector. The only safe way to tell is to have a qualified contractor check. DO NOT attempt to check them yourself.
Moving the appliance, even slightly, whether to clean behind it or to inspect its gas connector, can cause complete failure of an older weakened connector and possibly result in a gas leak inside your home.
Appliance connectors can be purchased at any hardware or home improvement store. However, a qualified contractor should always install them.
Only a qualified professional should check or replace connectors.
As a rule, you should replace the connectors whenever the appliance is replaced or moved from its location.
To our knowledge, these dangerous uncoated brass connectors have not been made for more than 20 years, although it is always good to have them inspected.
We suggest that you arrange for an inspection through your landlord or property management company.
Only have a qualified HVAC contractor inspect and install appliance connectors.
Although not all uncoated connectors have this flaw, it is very difficult to tell which ones do. Therefore, any uncoated brass connector should be replaced immediately with a new plastic-coated brass connector or a new stainless steel connector. We have been telling customers about appliance connector hazards for several years. Because this is such an important safety issue, we are increasing efforts to make customers aware of the dangers.
