Schaefer Brush 08545-12 Power Fitting Cleaning Brush

Product Description

The SCHAEFER BRUSH 08545-12 is a carbon steel power fitting and cleaning brush designed for deburring, cleaning, and surface preparation of fittings and tubing in refrigeration and HVAC applications. The brush measures 3/8 inch inside diameter with a 9/16 inch actual brush diameter, making it sized for 1/2 inch refrigeration outside diameter work. The twisted wire stem provides durability under power tool rotation, and the 3/16 inch shank diameter fits standard power drill chucks and inline drivers. At 3-5/8 inches in overall length, it clears internal passages without overreaching tight access points. HVAC technicians and refrigeration mechanics keep this brush in rotation for pre-solder and pre-braze fitting prep on copper tubing and fittings.

This brush is suited for residential and light commercial refrigeration and HVAC service work. It handles interior fitting surfaces ahead of brazing or soldering operations, removing oxidation, flux residue, and particulate from copper fittings. The twisted wire construction holds its shape under rotary use, making it effective in a drill or power screwdriver. Technicians also use brushes of this type for cleaning valve bodies, port threads, and small-bore tubing ends where hand brushes lack the reach or speed to do the job efficiently.

Compatibility

Designed for use with 1/2 inch refrigeration outside diameter fittings and copper tubing ends in HVAC and refrigeration service applications.

Installation Notes

This brush is installed in a power drill or inline driver by HVAC technicians and refrigeration mechanics. Always de-energize and recover refrigerant from the system before opening any fittings for cleaning or replacement. Use eye protection when operating rotary wire brushes. Do not exceed the rated RPM of the brush or the chuck capacity of the drive tool.
