Clean-fit 64050 3/4 Inch Refrigeration Fitting Brush Handheld Double Spiral

Product Description

The Clean-Fit 64050 is a 3/4 inch refrigeration fitting brush designed for cleaning copper tubing and fittings before brazing, soldering, or flaring. HVAC technicians and refrigeration mechanics rely on this type of brush to remove oxidation, debris, and surface contaminants from the inside of fittings and the outside of tube ends. A properly cleaned joint is essential for leak-free connections in refrigerant lines, and this brush makes that prep work fast and reliable.

The 64050 belongs to the 6400 Series from Clean-Fit, which is part of the Mill-Rose family of fitting and tube cleaning tools. Mill-Rose has a long history of manufacturing brushes specifically engineered for plumbing and refrigeration applications. This brush features a double spiral construction that drives bristles evenly across the full surface of the fitting interior, ensuring consistent contact and thorough cleaning in a single pass.

The handheld design gives the technician direct control over cleaning pressure and angle. There are no additional handles or extensions required. The bristles are constructed from rugged steel or stainless steel, chosen specifically to handle the hardness of copper fittings without excessive wear. The 3/4 inch size fits standard 3/4 inch refrigeration fittings and matches common tubing sizes used in residential and commercial HVAC systems, heat pumps, refrigeration units, and related equipment.

Proper surface preparation before brazing or soldering directly affects joint strength and system reliability. Refrigeration brushes like the Clean-Fit 64050 are a standard part of any HVAC or refrigeration technician's toolkit. This brush is also available in other sizes including 1/4 inch, 3/8 inch, 1/2 inch, and 5/8 inch, making the 6400 Series a versatile option across multiple job types.
