Yes a medical 5 liter per minute output concentrator works well for brazing bicycle frames. My DeVilbiss has a brass B fitting that I can screw my brazing hose directly onto. Some concentrators have a barb fitting designed to hold clear tubing. In that case a barb to B fitting is necessary. They are commonly available. Some pros that use a huge rosebud flame will not get enough oxygen output out of a single concentrator.
