Schaefer Brush 14644 Brass Wire Tube Brush 3/8 in Single Spiral

Product Description

The SCHAEFER BRUSH 14644 is a single-spiral brass wire tube brush designed for cleaning and deburring the interior of small-diameter tubes, ports, and passages. The brush head measures 3 inches in length with a 3/8-inch diameter, and the full assembly extends to an overall length of 27 inches, giving technicians reach into deep or hard-to-access bores. The 0.005-inch brass wire fill is soft enough to avoid scoring softer base metals while still providing effective scrubbing action. The 0.145-inch brass shank provides a secure grip in rotary tools, drill chucks, or hand drivers. Plumbers, HVAC technicians, and refrigeration mechanics commonly use brushes of this type to clean tube ends, fitting seats, and heat exchanger passages before brazing or connection.

This brush is suited for light-duty tube cleaning applications in residential and light commercial HVAC, plumbing, and refrigeration work. The single-spiral construction and brass fill make it appropriate for use on copper, brass, and other non-ferrous tubing where steel wire would risk contamination or surface damage. It is well matched to tube cleaning tasks that precede soldering or brazing operations, where clean, oxide-free surfaces are required for reliable joints. The 27-inch overall length allows access to passages that shorter brushes cannot reach.

Key Features

• Brass wire fill at 0.005 inches diameter — cleans without scoring non-ferrous tube interiors
• 3-inch brush length with 3/8-inch diameter for small-bore tube cleaning
• 27-inch overall length for deep or restricted-access passages
• Single-spiral construction provides consistent contact around the tube wall
• 0.145-inch brass shank fits standard drill chucks and rotary tool collets

Compatibility

Designed as an OEM-style replacement brush for use in small-diameter tube cleaning applications typical of HVAC, plumbing, and refrigeration service work. No specific system or model compatibility is stated by the manufacturer for this brush.

Installation Notes

This brush is installed and operated by HVAC technicians, plumbers, and refrigeration mechanics using hand drivers or low-speed rotary tools. Always power down any system and isolate the tube or component from pressure before inserting a brush into a port or passage. Avoid running the brush at excessive rotational speeds, which can flare or distort the wire fill and reduce brush life. Wear appropriate eye protection when using wire brushes in rotary applications.
