Schaefer Brush 08548-12 Power Fitting Cleaning Brush

Product Description

The SCHAEFER BRUSH 08548-12 is a carbon steel power fitting and cleaning brush designed for deburring, cleaning, and surface preparation of fittings, tubes, and pipe ends in HVAC and refrigeration work. Built with a twisted wire stem, it spins in a power drill to clean the inside of fittings quickly and consistently. The brush has a 0.75 inch inside diameter target bore and an actual brush diameter of 15/16 inch, making it sized for standard 7/8 inch refrigeration outside diameter tubing. The 3/16 inch shank fits standard drill chucks. HVAC technicians and refrigeration service pros keep this type of brush in regular rotation for copper fitting prep before brazing.

This brush is used in residential and light commercial HVAC and refrigeration service for cleaning the inside of copper fittings and tubing ends prior to brazing or soldering. It removes oxidation, flux residue, and light burrs from fitting interiors. The overall length of 3-5/8 inches gives adequate reach for most standard coupling and elbow fittings encountered in field service work.
