Brush Research Mfg. B61 Brass Scratch Brush 9 Rows 10 Columns

Product Description

The BRUSH RESEARCH MFG. B61 is a brass-fill scratch brush built for surface preparation, cleaning, and light material removal on metal, pipe, and fittings. It features a straight-back wood handle and a stiff brass bristle configuration arranged in 9 rows and 10 columns, giving it consistent contact across the work surface. At 8.875 inches overall length with a trim length of 0.625 inches, the B61 is sized for controlled hand work. Brass bristles are non-sparking and resist corrosion, making this brush well-suited for use on copper, brass, and soft metal components without leaving ferrous contamination. Plumbers, HVAC technicians, and pipefitters commonly use this type of brush for flux application prep, fitting cleanup, and oxidation removal before soldering or brazing.

The B61 is used across residential and light commercial trade applications where hand brushing is required prior to joining, coating, or inspection. Typical scenarios include cleaning copper pipe ends and fittings before soldering, removing light oxidation from brass valves, and surface prep on aluminum or soft alloy components. The 2.625-inch brush width provides good coverage on standard pipe fittings and flat surfaces. The straight-back handle style allows direct downward pressure and is comfortable for extended use in tight mechanical spaces.

Key Features

• Brass bristle fill - non-sparking and non-ferrous, safe for use on copper, brass, and aluminum
• 9-row by 10-column bristle pattern for even surface contact
• Stiff bristle grade for effective oxidation and flux residue removal
• Straight-back wood handle, 8.875 inches overall length
• 2.625-inch brush width covers standard pipe fittings and valve bodies efficiently
• 0.625-inch trim length maintains stiffness under moderate hand pressure

Compatibility

Designed as a general-purpose hand scratch brush suitable for plumbing, HVAC, and pipefitting surface preparation tasks involving copper, brass, and soft metal components.

Installation Notes

This brush is a hand tool used by plumbers, HVAC technicians, and pipefitters during surface preparation before soldering, brazing, or mechanical joining. No power source is required. Always brush in a well-ventilated area when working with flux or removing oxidation from heated metals. Inspect bristles periodically for wear or splaying, as a deformed brush face reduces cleaning effectiveness.
