The brush head measures 2-1\/8 inches in diameter with crimped brass bristles extending 7 inches in length, providing aggressive mechanical scrubbing action to remove soot, scale, and debris from tube interiors. A standard wood handle extends the overall assembled length to 48 inches, giving technicians the reach needed for deeper tube runs without additional extensions. Licensed HVAC technicians and boiler service professionals are the primary installers of this tool.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for routine maintenance and seasonal cleaning of fire-tube boilers, furnace heat exchanger flues, and similar cylindrical passages where fouling reduces thermal efficiency. The 2-1\/8 inch diameter fits common tube bore sizes found in residential and light commercial boiler installations. A single spiral bristle configuration concentrates cleaning force along the tube wall during push-pull strokes, making it effective for dislodging compacted deposits in both vertical and horizontal tube orientations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-1\/8 inch brush diameter sized for standard boiler and furnace tube bores\u003c\/li\u003e\n  \u003cli\u003eCrimped brass bristles provide aggressive scrubbing without damaging tube walls\u003c\/li\u003e\n  \u003cli\u003e7 inch bristle length maximizes contact surface per stroke\u003c\/li\u003e\n  \u003cli\u003e48 inch overall length delivers reach for deeper tube cleaning without extensions\u003c\/li\u003e\n  \u003cli\u003eStandard wood handle offers a firm, comfortable grip during service work\u003c\/li\u003e\n  \u003cli\u003eSingle-spiral bristle configuration maintains consistent wall contact through the full stroke\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style maintenance brush for boiler flue tubes and furnace heat exchanger tubes with an approximate 2-1\/8 inch interior bore diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eBoiler and furnace cleaning should be performed by qualified HVAC or boiler service technicians following applicable local codes. Before servicing, shut down the boiler or furnace, allow all surfaces to cool completely, and isolate fuel and electrical supplies.
