title: Torch Brazing Copper to Copper
description: Lucas-Milhaupt will show how to braze copper tubing and fittings easily, with the help of Sil-Fos® filler metals.  Note that no flux is required, because the phosphorus in Sil-Fos provides a self-fluxing ability when used with copper.

In about four minutes, this technical video will give you an up-close, step-by-step view of successful copper-to-copper brazing.  You will learn these important steps to achieving strong, reliable joints:

1.      Clean tubing and fitting, removing burrs and contaminants

2.      Insert the tube, with a consistent gap

3.      Apply heat and alloy, using a reducing flame

4.      Allow alloy to be drawn into joint interface, via capillary action
