Schaefer Brush 09545-12 Power Fitting Cleaning Brush

Product Description

The SCHAEFER BRUSH 09545-12 is a carbon steel power fitting and cleaning brush designed for use with rotary tools and drill-mounted applications. The brush features a 3/8 inch inside diameter and a 9/16 inch actual brush diameter, making it sized for cleaning and deburring 1/2 inch refrigeration fittings and tubing connections. The 1/4 inch shank diameter fits standard drill chucks and hex-drive adapters. At 3-1/8 inches in overall length with a hex shaft stem, it delivers consistent contact and torque transfer during power-driven cleaning operations. Weighing just 0.03 pounds, it is a compact, single-piece tool suited for HVAC and refrigeration service work.

This brush is used in HVAC and refrigeration applications where copper tubing, fittings, or valve seats require mechanical cleaning before brazing or connection. It is well suited for field service technicians preparing refrigerant line fittings, sweat joints, or port connections on residential and light commercial systems. The hex shaft stem allows use with quick-change bit holders, speeding up repetitive cleaning tasks on the job site.

Installation Notes

This brush is installed and used by HVAC and refrigeration technicians as part of pre-braze or pre-connection surface preparation. Always de-energize and isolate the refrigeration system before performing mechanical cleaning on fittings or valves. Use appropriate eye protection when operating power-driven wire brushes, as bristles can shed under load. Confirm the drill or driver chuck is fully tightened on the 1/4 inch shank before operating at speed.
