Brush Research Mfg. 93AP Scratch Brush Stainless Steel

Product Description

The BRUSH RESEARCH MFG. 93AP is a hand-held scratch brush designed for surface cleaning, deburring, and light abrasion work on metal, pipe, fittings, and related components. It features a 2-row, 7-column configuration of crimped stainless steel fill material seated in a curved back plastic handle. The overall length measures 7-1/4 inches, making it a compact, single-hand tool suited for close-quarters work. The curved back handle provides a positive grip during scrubbing strokes. Stainless steel bristles resist corrosion and hold up to repeated use on metal surfaces without contaminating the base material. Plumbers, HVAC technicians, pipefitters, and electricians keep this type of brush on hand for joint prep and general surface conditioning tasks.

The 93AP scratch brush is appropriate for a wide range of trade applications including flux removal from soldered copper fittings, light rust removal from pipe threads, cleaning electrical contact surfaces, and prepping metal for inspection or coating. Its compact size allows use in tight spaces such as valve bodies, junction boxes, and confined pipe runs. The stainless steel bristle material makes it suitable for use on stainless, copper, and carbon steel surfaces where cross-contamination from carbon steel wire must be avoided. This brush is sold individually and is intended for professional trade use in plumbing, HVAC, electrical, and mechanical service environments.

Designed as a general-purpose hand scratch brush suitable for surface preparation and cleaning tasks in plumbing, HVAC, electrical, and mechanical trade applications wherever a stainless steel bristle brush is required.

Installation Notes

No power tools or special equipment are required to use this brush. Apply moderate, consistent pressure during scrubbing strokes to avoid splaying the bristles prematurely. When used near live electrical components, ensure the circuit is de-energized per NEC guidelines before any cleaning work begins. Inspect bristles before each use and replace the brush if fill material shows significant wear or bristle loss.
