Schaefer Brush 09748-12 Power Fitting Cleaning Brush

Product Description

The SCHAEFER BRUSH 09748-12 is a stainless steel power fitting and cleaning brush designed for mechanical cleaning of fittings, ports, and tubing in refrigeration and HVAC applications. It features a 3/4 inch inside diameter with a 15/16 inch actual brush diameter and a 1/4 inch shank diameter, making it compatible with standard power drill chucks. The hex shaft stem provides positive engagement and reduces slippage during use. At 3-1/8 inches in length and rated to 2000 RPM, this brush handles both light deburring and residue removal in tight service environments.

This brush is suited for refrigeration technicians and HVAC service professionals cleaning fitting interiors, tube ends, and port openings prior to brazing or connection. The 7/8 inch refrigeration outside diameter corresponds to common refrigeration line sizing. It is well-suited for both residential and light commercial refrigeration service work where consistent surface preparation is required before flaring, swaging, or fitting assembly.

Installation Notes

This brush is installed and operated by HVAC-R technicians using a standard power drill or screwdriver with a 1/4 inch chuck. Always confirm the tool is set to a speed within the 2000 RPM maximum before operation. Wear appropriate eye protection when using rotary wire brushes. Ensure the fitting or tube end is secure and the system is depressurized before cleaning any refrigerant-side components.
