Good and Bad Connectors

Gas appliance connectors are corrugated metal tubes used to connect gas appliances to fuel supply pipes. Some older brass connectors have come apart, causing a gas leak leading to fires and explosions.

Examples of unacceptable uncoated brass appliance connectors:

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   

Examples of acceptable appliance connectors:

Uncoated, stainless steel connector
Coated stainless steel connector
Coated stainless steel connector

All appliances should be inspected for uncoated brass appliance connectors. Most dryers, ranges, ovens and cook tops have flexible appliance connectors as opposed to hard piping. 

Dryer with uncoated brass connector - unacceptable
Dryer with coated stainless steel connector - acceptable
Stove with uncoated brass connector - unacceptable
