Before a copper joint is brazed or soldered, the inside of the fitting socket must be scrubbed bright. This fitting brush is made for that job on fittings and tubing up to 3/4 in. It is carbon steel with steel bristles and a plastic handle. At 4 3/4 in (120 mm) long, it is short enough to work into a socket on a line already in place.

Brazing Practicals for Refrigeration Students
Joint preparation is the first lesson in brazing. Students cut and ream a length of Copper Pipe, then polish the outside of the end with an Abrasive Strip (Sand Paper). The brush is twisted inside the socket of a Flare To Solder Fitting until the metal is bright all round.
The joint is then assembled and brazed with Brazing Rod while dry nitrogen flows through the pipe. Teachers often braze an uncleaned joint beside a cleaned one. When both are cut open, the dirty joint shows gaps where the alloy did not run.
Frequently Asked Questions
What size of fitting does the brush clean?
It is made for fittings and tubing up to 3/4 in. The brush goes into the socket and is turned until the whole inner surface that the tube will touch is bright.
Why clean a fitting before brazing or soldering?
Oxide, grease and dirt stop the filler metal from wetting the copper. On a clean surface, capillary action draws the molten alloy right through the joint gap. A dirty socket leaves voids that can leak later.
Should the brush be used with oil or solvent?
No. Use it dry, and keep it away from oil and flux so it does not carry dirt back into a cleaned socket. Once a fitting is clean, do not touch the inside with your fingers.
Can it be used on flat surfaces as well?
It is shaped for the inside of sockets and tubing. For open surfaces, plate edges and weld areas, the Steel Brush with straight stainless steel wire and a wooden handle is the better tool.
