Brush Research Mfg. 93APN Scratch Brush Nylon 2 Row 7 Column

Product Description

The BRUSH RESEARCH MFG. 93APN is a nylon-fill scratch brush designed for surface preparation, cleaning, and light deburring on metal, plastic, and composite materials. It features a 2-row, 7-column crimped nylon bristle configuration that provides consistent scrubbing action across the work surface. The curved back handle is molded from black plastic, giving the user a secure grip during repetitive hand operations. At 7.25 inches overall length and weighing under a tenth of a pound, it is a lightweight, task-specific hand tool suited for technicians and tradespeople who need a reliable scratch brush for shop or field use.

This scratch brush is used in HVAC, plumbing, electrical, and general mechanical applications where surface cleaning, flux application prep, corrosion removal, or light abrasion is required before joining, sealing, or fastening components. It is appropriate for both bench work and in-place service tasks. The nylon fill makes it suitable for use on softer metals and surfaces where steel bristles would cause damage or contamination. Typical users include HVAC technicians, plumbers, and electricians working on fittings, terminals, and pipe surfaces.

Installation Notes

No power source or special tools are required for use. Inspect bristles before each use and replace the brush when fill material shows significant wear or deformation. Keep the bristle area free of grease and solvent buildup that could degrade nylon fill over time. Dispose of used brushes in accordance with local shop waste guidelines, particularly if used with flux or chemical cleaning agents.
