Built with a standard wood handle and a single spiral bristle configuration, it gives technicians firm, consistent contact across the interior surfaces of heat exchangers and flue passages. The brush head measures 3 inches in diameter with a 6-inch bristle length, and the overall assembly reaches 27 inches to provide safe working distance from heat-affected surfaces. At 0.4 pounds, it is lightweight enough for extended overhead or confined-space use. HVAC service technicians and boiler maintenance crews are the primary installers and users.\u003c\/p\u003e\u003cp\u003eThis brush is suited for routine maintenance cleaning of residential and light commercial boilers and furnaces. It is used to remove soot, scale, and combustion deposits from flue tubes, heat exchanger passages, and firebox walls. The 27-inch overall length allows access into deeper flue sections without requiring additional extension tools in most standard residential applications. It is a standard tool in annual boiler tune-up and combustion efficiency service procedures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-inch brush diameter for flue tube and combustion chamber cleaning\u003c\/li\u003e\n\u003cli\u003e6-inch bristle length provides thorough surface contact in cylindrical passages\u003c\/li\u003e\n\u003cli\u003eFiber and hair bristle construction resists heat and flexes to conform to tube walls\u003c\/li\u003e\n\u003cli\u003eSingle spiral bristle pattern delivers even scrubbing pressure\u003c\/li\u003e\n\u003cli\u003eStandard wood handle with 27-inch overall length for extended reach\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.4 pounds for easy single-hand control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style maintenance brush for residential and light commercial boiler flue tubes and furnace combustion chambers requiring a 3-inch diameter cleaning tool.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAlways shut down and allow the boiler or furnace to cool completely before performing any flue or combustion chamber cleaning.
