Schaefer Brush 76246 Boiler Furnace Brush 3 in 42 in Oal

Product Description

The SCHAEFER BRUSH 76246 is a boiler and furnace flue brush designed for cleaning fireboxes, flue passages, and heat exchanger tubes in residential and light commercial heating equipment. The brush head measures 3 inches in diameter with a 6-inch bristle length, providing thorough contact across standard flue openings and tube bores. Bristles are constructed from a fiber and hair blend that conforms to irregular surfaces while sweeping out soot, scale, and combustion deposits. The standard wood handle extends the overall length to 42 inches, giving technicians adequate reach into vertical or horizontal flue runs without additional extensions on most residential appliances.

This brush is suited for routine maintenance cleaning of boiler flue passages, furnace heat exchangers, and similar heating system components. HVAC technicians and heating service pros typically deploy it during annual tune-ups and pre-season inspections to clear carbon buildup and debris from combustion chambers and connected flue runs. The 42-inch overall length handles most standard residential boiler and furnace depths without the need for an extension handle.
