Schaefer Brush 09548-12 Power Fitting Cleaning Brush

Product Description

The SCHAEFER BRUSH 09548-12 is a carbon steel power fitting and cleaning brush designed for use with rotary power tools via its 1/4-inch hex shaft stem. The brush measures 3/4 inch inside diameter with a 15/16-inch actual brush diameter, a 7/8-inch refrigeration outside diameter, and an overall length of 3-1/8 inches. It is used to clean and deburr copper fittings, tube ends, and refrigeration connections prior to soldering or brazing. HVAC technicians and refrigeration service pros are the primary installers and users of this type of brush.

This brush is suited for refrigeration and HVAC service work where clean, oxide-free fitting surfaces are required before joining. The hex shaft stem accepts standard 1/4-inch quick-change drill adapters and power screwdrivers, making it a fast alternative to hand-twist brushes. It is sized for 3/4-inch copper tube and fittings common in residential and light commercial refrigerant piping and plumbing applications.

Installation Notes

HVAC technicians and plumbers use this brush with a power drill or impact driver fitted with a 1/4-inch hex adapter. Always power down and de-energize any associated equipment and relieve system pressure before cleaning fittings in an active refrigerant or plumbing circuit. Keep rotational speed within the tool and brush manufacturer recommendations to avoid bristle damage or excessive heat buildup. Follow applicable mechanical codes and safety practices when preparing joints for brazing or soldering.
