What is the recommended diameter for a flexible gas connector?

The recommended diameter for a flexible gas connector is typically 1/2 inch. This size is most commonly used for residential gas appliances and provides an adequate capacity to deliver gas without excessive pressure loss. A 1/2-inch diameter is compatible with standard gas pipe fittings and is suitable for various applications, including ranges, water heaters, and other appliances that require gas supply.

Selecting a diameter that is too small can restrict gas flow, leading to insufficient gas supply during appliance operation, which can result in poor performance or even safety hazards. On the other hand, opting for a diameter larger than necessary may not provide additional benefits and could increase installation costs and complexity.

It's important for contractors and plumbing professionals to adhere to local codes and manufacturer specifications when choosing gas connectors to ensure safe and efficient gas delivery. Recognizing the significance of using the correct size contributes to the overall effectiveness and safety of gas installations.
