Soldering Products

You won't find a better selection of high quality solder and flux, copper fittings, and other copper-related products anywhere on the Internet.

The strong acid in plumbing solder is very corrosive in order to strip the layer of oxidation off the surface of pipes as the solder melts, allowing it to adhere and form a waterproof joint.
