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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch brush diameter sized for standard residential boiler and furnace flue passages\u003c\/li\u003e\n  \u003cli\u003e6-inch bristle length for deep, thorough contact inside tube bores and fireboxes\u003c\/li\u003e\n  \u003cli\u003eFiber and hair bristle blend conforms to irregular interior surfaces\u003c\/li\u003e\n  \u003cli\u003eSingle spiral bristle wrap provides uniform coverage around the full brush circumference\u003c\/li\u003e\n  \u003cli\u003eStandard wood handle with 42-inch overall length for deep-reach access\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.63 pounds for extended overhead or confined-space use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and maintenance brush for residential and light commercial boilers and furnaces with flue passages or heat exchanger tubes accommodating a 3-inch diameter brush head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this brush should be performed by a licensed HVAC technician or qualified heating service professional.
