Schaefer Brush 08743-12 Power Fitting Cleaning Brush

Product Description

The SCHAEFER BRUSH 08743-12 is a stainless steel power fitting and cleaning brush designed for cleaning refrigeration fittings, ports, and small-diameter passages in HVAC and refrigeration systems. It features a 1/8 inch shank diameter for use with standard power drills and rotary tools, a twisted wire stem construction for rigidity and flex resistance, and an overall length of 3-5/8 inches. The actual brush diameter measures 5/16 inch, sized to match 1/4 inch refrigeration outside-diameter fittings. HVAC technicians and refrigeration service pros use this brush during line set preparation, fitting cleaning, and port deburring tasks.

This brush is suited for residential and light commercial refrigeration and HVAC service work where fitting cleanliness is critical to a proper brazed or flared connection. The 1/8 inch inside diameter bore sizing and 1/4 inch refrigeration OD fitment make it appropriate for standard refrigerant line fittings and small-diameter copper connections. It is typically used during system installation, repair, or changeover when fittings must be cleaned of oxidation, debris, or residue before assembly.

Key Features

• 1/8 inch shank diameter fits standard drill chucks and rotary tool collets for powered cleaning
• Twisted wire stem provides rigidity while allowing the brush to follow fitting contours
• 3-5/8 inch overall length gives adequate reach into fittings and ports

Installation Notes

This brush is installed into a drill chuck or rotary tool by a licensed HVAC or refrigeration technician. Always recover or isolate refrigerant and depressurize the system before cleaning open fittings. Wear appropriate eye protection when using rotary cleaning tools. Inspect the twisted wire stem for wear or unraveling before each use and replace the brush if the stem shows signs of damage.
