Short answer
The connector is the short gas line between the wall shutoff and an appliance. SoCalGas advises replacing semi-rigid aluminum or copper tubing connectors with approved flexible ones. Kinked, corroded or very old connectors should be replaced too.

What SoCalGas recommends
SoCalGas's home energy and safety guide advises replacing any semi-rigid aluminum or copper tubing appliance connector with an approved flexible connector.
The same guide says connectors should not pass through floors, walls or ceilings, where they can be damaged.
Where to check
Pull the range forward carefully, look behind the dryer, and look at the line feeding the water heater and furnace.
Many SGV homes date from the 1950s and 1960s, with Monterey Park's median at 1963. Appliances there have been swapped several times, and the connectors not always.
How replacement works
The new connector is sized to the appliance and length needed, with proper fittings. Every joint is tested with leak solution before the appliance goes back.
Signs of a problem
- A gas smell near the appliance
- Hissing near the connector
- A flame that is yellow or lazy instead of blue
If you smell gas strongly, leave and call SoCalGas from outside before anything else.
Common questions
Can I reuse a connector when moving a stove?
Makers generally say no. Fit a new connector when an appliance is replaced or moved.
What length connector should I use?
The shortest that reaches without strain or sharp bends.
Do dryers need a special connector?
They use a gas appliance connector rated for the dryer's input. Length and fittings vary.
