Schaefer Brush 08746-12 Power Fitting Cleaning Brush

Product Description

The SCHAEFER BRUSH 08746-12 is a stainless steel power fitting and cleaning brush designed for use with rotary tools and drill-powered cleaning applications in HVAC and refrigeration service work. The brush features a 0.5 inch inside diameter and an 11/16 inch actual brush diameter, making it well suited for cleaning fittings, tube ends, and small-bore passages. A twisted wire stem construction provides durability and flexibility under power. The 3/16 inch shank diameter is compatible with standard chuck sizes used in portable drills and rotary tools commonly found in HVAC and refrigeration service kits.

This brush is used in residential and light commercial HVAC and refrigeration service applications where fitting surfaces and tube interiors need to be cleaned prior to brazing, flaring, or connection. The 3-5/8 inch overall length provides enough reach for most service scenarios without excessive flex. With a 5/8 inch refrigeration outside diameter rating, it is appropriate for cleaning standard 5/8 inch OD refrigeration tubing and fittings. HVAC technicians, refrigeration mechanics, and plumbers performing brazing prep work are the typical end users.
