AG30% Silver Solder Brazing Rods30% silver content brazing rods from Lawton Tubes, supplied in 500mm lengths. A high-performance brazing alloy offering excellent flow, joint strength, and ductility. Suitable for demanding HVAC, refrigeration, and industrial applications where a reliable, high-integrity joint is required.Key Features 30% silver content — high-strength, high-ductility brazing alloy 500mm rod length — standard trade length Excellent flow and wetting on copper, brass, and steel Produces strong, leak-free joints suitable for pressurised refrigeration systems Preferred choice for professional HVAC and refrigeration engineers How to Braze Copper Fittings Cut tube square using a pipe cutter or fine hacksaw (32 TPI). Remove burr with file or scraper. Clean outside of copper tube thoroughly with sand cloth or sandpaper to the depth of the fitting. Leave no dark spots. Clean inside of fitting carefully to tube stop with a wire brush. Sand cloth or sandpaper may also be used. Apply heat uniformly around the fitting with a torch. When the brazing rod melts on contact with the heated fitting, the correct brazing temperature has been reached. Remove flame and feed rod to the joint at one or two points until a ring of brazing alloy appears at the end of the fitting. Note: Always work in a well-ventilated area and follow appropriate safety precautions when brazing.
