Schaefer Brush 43214 Flue Brush 1-1/2 in Dia 7-1/2 in Oal

Product Description

The SCHAEFER BRUSH 43214 is a double stem, single spiral flue brush designed for cleaning flue pipes, heat exchangers, and venting passages in heating systems. The brush features a tempered steel wire spiral construction that provides firm, consistent contact with flue wall surfaces to break loose and remove soot, scale, and carbon buildup. At 1-1/2 inches in diameter with a 4-1/2 inch brush length and 7-1/2 inches overall length, this tool is sized for standard residential flue and vent pipe cleaning applications. It connects via a 1/4 inch NPSM male fitting, making it compatible with standard extension rods. HVAC technicians and chimney service professionals use this brush as part of routine combustion system maintenance.

This flue brush is suited for residential and light commercial heating system service. It is typically used to clean flue liners, vent connector pipes, and draft diverter passages in gas, oil, and solid-fuel appliances. The double stem design provides structural rigidity during use, allowing the brush to maintain its spiral profile when pushed or rotated through flue passages. It is a standard service item for seasonal tune-ups and combustion efficiency inspections.
