How to Solder Copper Fittings

1. Cut and deburr — cut the copper pipe cleanly and remove the internal burr with a reamer or deburring tool.
2. Clean — clean the pipe end and fitting socket with wire wool or emery cloth until bright.
3. Apply flux — apply Lawton flux paste to both the pipe end and fitting socket using the brush in the cap.
4. Heat evenly — apply heat evenly around the fitting with a blowtorch until the flux bubbles and the copper reaches soldering temperature (220°C).
5. Apply solder — touch the solder wire to the joint (not the flame). The solder will be drawn in by capillary action. Apply until a complete ring is visible around the fitting.
6. Cool and clean — allow to cool undisturbed. Wipe away flux residue with a damp cloth.
