Ampco B-400 Scratch Brush Bronze 4 Row 19 Column

Product Description

The AMPCO B-400 is a bronze-fill scratch brush designed for surface preparation, cleaning, and light deburring tasks in trade and industrial settings. Built with 4 rows and 19 columns of bronze bristles, it delivers consistent abrasive coverage across the work surface. The curved wood handle provides a natural grip angle for extended use. Bronze fill is preferred in environments where spark resistance or non-ferrous contact is required, making this brush suitable for use around flammable materials or on softer metal surfaces where steel bristles would cause damage.

This scratch brush is used across plumbing, HVAC, electrical, and general mechanical trades for cleaning pipe ends, flux residue, oxidation, and corrosion from metal surfaces before brazing, soldering, or electrical termination. The curved handle suits close-quarter scrubbing where a straight-handle brush is harder to control. It is appropriate for both shop bench work and field service applications.

Key Features

• Bronze bristle fill for spark-resistant, non-ferrous surface cleaning
• 4-row by 19-column bristle configuration for broad, even coverage
• Curved wood handle for improved grip angle and control

• Lightweight at 0.55 pounds for easy single-hand use
• Sold individually - one brush per package

Compatibility

Designed as a general-purpose scratch brush suitable for use on copper, brass, aluminum, and other non-ferrous metal surfaces in plumbing, HVAC, and electrical trade applications.

Installation Notes

No power source or system shutdown is required for use of this hand tool. When used for flux or oxidation removal prior to soldering or brazing, follow applicable codes and ensure the work area is clear of ignition sources before applying heat. Wear appropriate eye protection when brushing to prevent bristle fragments or debris from becoming a hazard. Inspect bristles before each use and replace the brush if fill material shows significant wear or bristle loss.
