Which material may be used on oil piping in residential installations?

• A. Rigid steel
• B. Flexible connectors
• C. PVC pipe
• D. Copper tubing

Answer: (B)

Oil piping must be compatible with petroleum fuels and able to handle movement and temperature changes in a residential setting. Flexible connectors are designed specifically for this purpose, providing a compliant link between the fuel supply line and the burner while absorbing vibration, expansion, and minor misalignment. This helps prevent leaks and stress on joints, which is why they’re the appropriate choice for the connection segment of an oil system. Rigid steel piping is used for much of the main run, but the flexible connector is the part that may be used to connect to the appliance and tolerates movement. PVC pipe is not suitable for oil because petroleum fuels can degrade it and it isn’t rated for the temperatures or pressures involved. Copper tubing is generally not employed for oil lines in residential installations due to compatibility and code considerations.
