Brush Research Mfg. 93APB Scratch Brush 2 Row 7 Column

Product Description

The BRUSH RESEARCH MFG. 93APB is a hand scratch brush designed for surface preparation, cleaning, and deburring on metal, pipe fittings, and mechanical components. It features a 2-row, 7-column fill pattern of crimped brass and stainless steel bristles, delivering consistent scrubbing action across the work surface. The curved back handle is molded from black plastic and sized for single-hand operation. At 7.25 inches overall length, it fits comfortably for close-quarters work. HVAC technicians, plumbers, and pipefitters use scratch brushes like this for flux application prep, joint cleaning, and removing light oxidation before soldering or brazing.

The 93APB is suited for residential and light commercial trade work where surface cleanliness directly affects joint integrity. Common applications include cleaning copper pipe ends before soldering, removing corrosion from fittings, prepping threaded connections, and general-purpose surface abrasion on ferrous and non-ferrous metals. The dual-material bristle fill - brass and stainless steel - provides versatility across soft and hard base materials without cross-contamination concerns when kept dedicated to one material type.

Installation Notes

Scratch brushes are a consumable hand tool requiring no installation. Licensed plumbers and HVAC technicians should select bristle material compatible with the base metal being worked - avoid using a shared brush on dissimilar metals to prevent contamination. Always wear appropriate eye protection when using wire-type scratch brushes, as bristles can shed under load. Dispose of brushes when bristle fill shows significant splaying or loss.
