Schaefer Brush 08544-12 Power Fitting Cleaning Brush

Product Description

The SCHAEFER BRUSH 08544-12 is a carbon steel power fitting and cleaning brush designed for use with rotary power tools in HVAC, refrigeration, and plumbing applications. It features a 0.25 inch inside diameter with a 7/16 inch actual brush diameter, a 3/16 inch shank diameter, and a twisted wire stem construction. Overall length is 3-5/8 inches. The brush is rated for 3/8 inch refrigeration outside diameter fittings. HVAC technicians and plumbers use this brush to clean copper fittings, tube ends, and refrigerant line connections prior to brazing or soldering.

This brush is suited for residential and light commercial service work involving copper refrigerant lines and plumbing fittings. It is commonly used during installation and maintenance of refrigeration systems, air conditioning equipment, and potable water piping where clean, oxide-free joint surfaces are required for reliable solder or braze connections. The shank design allows use with a standard power drill or rotary tool for faster fitting prep compared to hand brushes.
