The brush head measures 0.75 inches in diameter with a 4-inch bristle length, giving it enough reach and stiffness to dislodge soot, scale, and carbon deposits from tight passages. The wire loop handle extends the overall assembly to 42 inches, providing the reach needed to service deep flue passages and tube bundles without requiring additional extensions in many standard installations. The stainless steel construction on both the brush head and bristles resists corrosion from combustion byproducts and moisture exposure.\u003c\/p\u003e\u003cp\u003eThis brush is suited for boiler and furnace maintenance tasks where access to narrow flue tubes, firetubes, or heat exchanger passages is required. Typical applications include annual or seasonal cleaning of fire-tube boilers, residential and light-commercial furnace flue passages, and similar combustion equipment requiring internal brush cleaning. The 0.75-inch diameter profile fits standard small-bore flue tubes and heat exchanger passages common in gas and oil-fired heating systems. HVAC service technicians and boiler mechanics are the primary installers and users of this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.75-inch brush diameter sized for standard small-bore flue tubes and heat exchanger passages\u003c\/li\u003e\n\u003cli\u003e4-inch bristle length provides effective contact area for thorough soot and scale removal\u003c\/li\u003e\n\u003cli\u003e42-inch overall length allows deep reach into boiler and furnace flue passages\u003c\/li\u003e\n\u003cli\u003eStainless steel bristles and brush construction resist corrosion from combustion residue and moisture\u003c\/li\u003e\n\u003cli\u003eSingle-spiral bristle configuration for consistent cleaning coverage\u003c\/li\u003e\n\u003cli\u003eWire loop handle provides a secure grip during push-pull cleaning strokes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in boiler and furnace flue tube cleaning applications where a 0.75-inch diameter brush is the appropriate fit for the passage being serviced.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAlways shut down and allow the boiler or furnace to cool completely before inserting any cleaning brush into flue passages or heat exchanger tubes. HVAC technicians and boiler mechanics should follow applicable service procedures and local codes when performing combustion equipment maintenance. Inspect the brush for bent or broken bristles before each use and replace if damaged, as loose wire bristles can lodge inside flue passages. Wear appropriate eye and respiratory protection when cleaning soot and combustion deposits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBristle Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 42 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBristle Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Bristle Spirals\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Wire Loop\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.46 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCHAEFER BRUSH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 76253\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51542648160562,"sku":"76253","price":20.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/acce3b19e56becdb6484667565eecd36_dc0143be-ef4e-4a3a-9d06-1c91537cd559.jpg?v=1785904138","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-76253-boiler-furnace-stainless-steel-brush","provider":"Voomi Supply","version":"1.0","type":"link"}
