Natural gas travels from your home's supply pipes to movable appliances such as stoves, ranges, clothes dryers and portable room heaters via flexible, corrugated metal connectors. If your gas appliances were installed before 1980, be sure to check the condition of the appliance connectors.
Before 1980, these connectors were made of uncoated brass. Over time, the tubing in uncoated brass connectors can separate from the ends, causing a leak that could lead to a fire or explosion. Although no longer manufactured, uncoated brass connectors are still in use in some homes and should be replaced.
If you think you have uncoated brass connectors, call a qualified professional to replace them with today's modern, sturdier stainless steel or plastic-coated brass flex connectors. Don't try to move your appliances yourself because the connector may break.
