Schaefer Brush 08745-12 Power Fitting Cleaning Brush

Product Description

The SCHAEFER BRUSH 08745-12 is a twisted wire stem cleaning brush designed for power fitting and tube cleaning applications in refrigeration and HVAC service work. It features a 3/8 inch inside diameter with a 9/16 inch actual brush diameter and stainless steel bristles that hold up to repeated use in metal fittings, copper tube ends, and refrigeration line components. The 3/16 inch shank diameter makes it compatible with standard power drill chucks and rotary tools. At 3-5/8 inches in length, it provides enough reach for common fitting and tube prep tasks without excessive flex.

This brush is used by HVAC and refrigeration technicians for cleaning the inside of fittings, tube ends, and port openings prior to brazing, flaring, or reconnection. It is suited for residential and light commercial refrigeration service where thorough mechanical cleaning of a 1/2 inch refrigeration outside diameter connection is required. The stainless steel construction resists corrosion from refrigerant oils, flux residue, and moisture encountered in the field.

Key Features

Compatibility

Designed for use with 1/2 inch refrigeration outside diameter fittings and tubing connections. Suitable for general HVAC and refrigeration fitting cleaning applications where a 3/8 inch inside diameter brush is required.

Installation Notes

Installation of this brush is performed by HVAC and refrigeration technicians as part of fitting preparation and tube cleaning procedures. Chuck the 3/16 inch shank securely into a power drill or rotary tool before use and confirm the chuck is fully tightened. Always wear eye protection when operating rotary cleaning brushes, as wire bristles and debris can dislodge at speed. Ensure the system is fully de-pressurized and isolated before cleaning any refrigerant-side fittings or components.
