Schaefer Brush 09746-12 Fitting Cleaning Brush 0.5in Id

Product Description

The SCHAEFER BRUSH 09746-12 is a stainless steel power fitting and cleaning brush designed for use with a drill or rotary tool via its 1/4-inch hex shank stem. The brush measures 0.5 inches inside diameter with an actual brush diameter of 11/16 inches and an overall length of 3-1/8 inches. The 5/8-inch refrigeration outside diameter makes it well suited for cleaning refrigeration fittings, tube ends, and port surfaces before assembly or brazing. HVAC technicians and refrigeration service pros reach for this brush when preparing copper fittings and tubing connections for leak-free joints.

This brush is used in refrigeration and HVAC service applications where fitting surfaces must be clean and free of oxidation, debris, or residue before soldering or brazing. The hex shaft stem accepts standard 1/4-inch power tool chucks, allowing fast, consistent surface prep on fittings, valves, and tube ends encountered in residential and light commercial refrigeration and air conditioning work.

Key Features

• Stainless steel bristles resist corrosion and maintain stiffness during aggressive cleaning
• 0.5-inch inside diameter targets standard refrigeration fittings and tube ends
• 11/16-inch actual brush diameter provides full contact with fitting interiors
• 1/4-inch hex shank mounts directly in standard drill chucks or hex drivers
• 3-1/8-inch overall length keeps the tool clear of surrounding components during use
• 5/8-inch refrigeration outside diameter matches common copper fitting sizes

Compatibility

Designed for use on standard refrigeration and HVAC fittings with a 0.5-inch inside diameter, consistent with common 1/2-inch copper tube and fitting sizes used in refrigeration and air conditioning systems.

Installation Notes

This brush is typically used by HVAC and refrigeration technicians during fitting preparation before soldering or brazing. Always recover refrigerant and depressurize the system before working on fittings or tube connections. Wear appropriate eye protection when operating rotary cleaning tools. Follow applicable refrigeration safety codes and manufacturer fitting preparation guidelines.
