What brazing rods are used for copper gas lines?

For brazing copper gas lines, the most commonly used brazing rods are those made from a copper-phosphorus alloy, such as AWS BCuP-3 or BCuP-5. These rods typically contain a low percentage of phosphorus, which acts as a fluxing agent and helps to promote strong joints without the need for additional flux. It's important to select rods that are appropriate for the specific application and ensure compatibility with the gas being transported. Always follow safety guidelines and manufacturer recommendations during the brazing process.
