What are gas appliance connectors?

1. Heavy-duty pipelines

2. Flexible tubes that connect gas appliances to the gas supply

3. Devices for monitoring gas pressure

4. Permanent installations for gas lines

The correct answer is: Flexible tubes that connect gas appliances to the gas supply

Gas appliance connectors are specifically designed to link gas appliances, such as furnaces, water heaters, and ranges, to the gas supply. They play a vital role in ensuring a safe and efficient flow of gas from the supply line to the appliance. The flexibility of these connectors allows for easier installation, movement of the appliance for maintenance, and adaptability in tight spaces, which is essential in both residential and commercial settings. In contrast, heavy-duty pipelines refer to rigid systems designed for transporting gas over long distances and typically involve more permanent installations. Devices for monitoring gas pressure are crucial for safety and operational efficiency but serve a different function than connectors, which do not measure or regulate pressure. Permanent installations for gas lines denote fixed piping systems that deliver gas but do not involve the flexible connection aspect provided by gas appliance connectors.
