Schaefer Brush 08748-12 Power Fitting Cleaning Brush

Product Description

The SCHAEFER BRUSH 08748-12 is a twisted wire stem cleaning brush designed for power fitting and tube cleaning in refrigeration and HVAC applications. The brush features a 3/4 inch inside diameter with a 15/16 inch actual brush diameter, allowing it to scrub the interior walls of fittings, ports, and tubing with consistent contact. The stainless steel bristles resist corrosion and stand up to repeated use in wet or oily service environments. Overall length is 3-5/8 inches with a 3/16 inch shank diameter, making it compatible with standard power drills and flex-shaft tools used in field service work. HVAC technicians and refrigeration mechanics rely on this style of brush to prepare fittings before brazing or to remove debris from tube bores.

This brush is suited for use in residential and light commercial refrigeration systems, HVAC equipment, and anywhere that tube or fitting interiors need to be cleaned before assembly or repair. The 7/8 inch refrigeration outside diameter spec aligns it with common ACR tubing and fitting sizes found in split systems, condensing units, and refrigeration circuits. The stainless steel construction makes it appropriate for use with refrigerant-grade fittings where contamination from carbon steel must be avoided.

Installation Notes

Installation of this brush requires no special trade licensing, but it is typically used by licensed HVAC technicians and refrigeration mechanics during system service or repair. Secure the 3/16 inch shank firmly in the drill chuck before operation to prevent ejection. Always power down and de-energize the equipment being serviced before accessing fittings or tube connections. Inspect bristle condition before each use and replace the brush if the wire stem or bristles show signs of deformation or fatigue.
