Schaefer Brush 14650 Brass Wire Tube Brush 3x3/4in 27in Oal

Product Description

The SCHAEFER BRUSH 14650 is a single-spiral brass wire tube brush designed for cleaning small-diameter tubes, ports, fittings, and passages in HVAC, plumbing, and refrigeration systems. The brush head measures 3 inches long with a 3/4-inch diameter, providing targeted scrubbing action inside narrow openings. The 0.006-inch brass wire fill is soft enough to clean without damaging softer base metals like copper tubing or brass fittings. A 27-inch overall length with a 3/8-inch shank gives technicians extended reach into manifolds, heat exchangers, and pipe runs without disassembly. Service techs and plumbers working on tube maintenance or connection prep are the primary users.

This brush suits residential and light commercial applications where tube and port cleaning is part of routine maintenance or repair. Common uses include clearing debris and oxidation from copper refrigerant lines, small-bore pipe threads, condensate drain fittings, and valve seats. The long handle makes it practical for reaching into equipment cabinets or tight mechanical spaces where short brushes cannot access the work area effectively.

Installation Notes

This brush is a hand-operated cleaning tool and does not require electrical isolation before use, though the system or component being cleaned should be depressurized and fully isolated before inserting the brush into any live tube or port. Wear appropriate PPE including eye protection when brushing oxidation or debris from tube interiors. Do not attach this brush to a power drill or rotary tool unless it is explicitly rated for rotary use, as doing so with a hand brush can cause filament separation and injury.
