Flexible Appliance Gas Connectors: Lifespan & Safety

Direct Service Resource: Need immediate professional assistance for this issue? Visit our dedicated Gas Safety Inspections page.

Flexible corrugated metal gas connectors connect your stationary gas supply to movable appliances like clothes dryers, kitchen stoves, and water heaters. While convenient, older connectors represent one of the most common causes of residential gas leaks in Southern California.

The Uncoated Brass Connector Recall Hazard

Homes built before 1990 often contain uncoated brass flexible connectors with soldered end fittings. Over time, household cleaning vapors and sulfur in natural gas cause the soldered joints to corrode and crack. The US Consumer Product Safety Commission (CPSC) issued urgent warnings to replace all uncoated brass connectors immediately.

The 10-Year Replacement Rule

Modern epoxy-coated stainless steel connectors have a maximum recommended lifespan of 10 years. Connectors should NEVER be reused when installing a new appliance. Moving an old flex line can cause micro-fissures along the corrugated ribs.
