Schaefer Brush 14642 Wire Tube Brush 3 in Brass Single Spiral

Product Description

The SCHAEFER BRUSH 14642 is a long-handle 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 0.25-inch brush diameter, and the assembly reaches an overall length of 27 inches, giving technicians the reach needed to clean deep into tubing runs, heat exchanger passages, and conduit bores. Brass fill wire at 0.005 inches in diameter provides effective scrubbing action without the risk of ferrous contamination or sparking, making it well-suited for copper, aluminum, and brass tubing commonly found in HVAC, refrigeration, and plumbing systems.

This brush is used in residential and light commercial applications where technicians need to clean or clear small-bore tubing, coil passages, orifice passages, or threaded ports prior to repair or reassembly. The single-spiral construction and 0.13-inch shank diameter allow it to seat into standard drill chucks or be worked by hand for controlled cleaning strokes. HVAC technicians, refrigeration mechanics, and plumbers will find this tool useful during maintenance, repair, and new installation work where tube cleanliness is critical to joint integrity or flow performance.

Key Features

• 3-inch brush length and 0.25-inch brush diameter for small-bore tube cleaning
• 27-inch overall length provides extended reach into deep tubing runs and passages
• Brass fill wire at 0.005 inches resists sparking and prevents ferrous contamination
• Single-spiral construction with one bristle spiral for consistent contact through the bore
• 0.13-inch brass shank diameter compatible with standard drill chucks or hand use

Compatibility

Designed for use with small-diameter tubes and passages measuring approximately 0.25 inches in inner diameter. Suitable for copper, brass, and aluminum tubing common in HVAC, refrigeration, and plumbing service work.

Installation Notes

This brush is a hand tool and requires no power shutdown before use, though standard shop safety practices apply when working near pressurized systems. Ensure the tube or passage to be cleaned is depressurized and drained before inserting the brush. The shank may be chucked into a low-speed drill for rotary cleaning or used manually for controlled hand strokes. Avoid applying excessive lateral force, which can deform the brush head or score soft tubing walls.
