What is a gas flex line?

A gas flex line is an approved flexible gas connector used to safely connect appliances—such as water heaters, ranges, dryers, fireplaces, and BBQs—to rigid gas piping.

When should a gas flex line be replaced?

Gas flex lines should be replaced if they are corroded, kinked, damaged, leaking, improperly sized, outdated, or not code-compliant for the appliance.

Are gas flex lines universal?

No. Gas flex lines vary by length, diameter, pressure rating, and application. Using the wrong type can create serious safety hazards.

Can old gas flex lines cause gas leaks?

Yes. Aging or improperly installed flex lines are a common source of gas leaks and should be inspected during appliance service or replacement.

Are gas flex lines required to meet code?

Yes. Gas flex lines must be approved for gas use, properly sized, correctly routed, and installed according to local and manufacturer code requirements.

Should a gas flex line be replaced when installing a new appliance?

Yes. Replacing the flex line during appliance installation is strongly recommended to ensure safety and compliance.

Are gas flex line services usually completed in one visit?

Most gas flex line installations or replacements can be completed in a single visit, depending on access and inspection requirements.
