Flexible Gas Connectors -
US Consumer Product Safety Commission Warning # 97-003
We recommend replacing 'brass corrugated metal tubing'
If you think you have a brass flexible connector in your home, have us replace it with a new one made of stainless steel. Do not attempt to move an appliance to inspect the connector because moving could strain the connector and possibly cause it to crack. Let us conduct an inspection.
It also is a good practice to have this inspected, and if necessary,
replace any flexible connector that is more than 10 years old.
