The brush head measures 2 inches in diameter with 6-inch fiber bristles that conform to tube and flue interior surfaces to dislodge soot, scale, and debris without scoring metal. A standard wood handle brings the overall assembled length to 42 inches, giving technicians the reach needed to service mid-depth boiler flue sections. HVAC and boiler service technicians keep this brush as standard kit for routine combustion-system cleaning.\u003c\/p\u003e\u003cp\u003eThis brush is suited for residential and light commercial boiler and furnace maintenance. It is commonly used during annual tune-ups and heat exchanger inspections to clean fire-side tube surfaces, flue passages, and combustion deposits. The 42-inch overall length makes it practical for accessing deeper flue sections without extension rods in many standard residential boiler configurations. The fiber bristle construction is appropriate for use on steel and cast-iron flue and boiler surfaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-inch brush diameter sized for standard boiler and furnace flue tube openings\u003c\/li\u003e\n\u003cli\u003e6-inch fiber bristle length provides thorough surface contact inside tubes and passages\u003c\/li\u003e\n\u003cli\u003eFiber bristles are non-metallic and will not score or scratch flue tube interiors\u003c\/li\u003e\n\u003cli\u003eSingle spiral bristle configuration for consistent cleaning coverage\u003c\/li\u003e\n\u003cli\u003e42-inch overall length delivers reach into mid-depth boiler flue sections\u003c\/li\u003e\n\u003cli\u003eStandard wood handle provides a firm, comfortable grip during service work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard service brush for boiler and furnace flue tube cleaning applications where a 2-inch diameter fiber brush is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis brush is installed and used by licensed HVAC technicians and boiler service professionals during scheduled maintenance or pre-season inspections. Always shut down the boiler or furnace and allow all surfaces to cool completely before inserting any cleaning tool into flue or heat exchanger passages. Verify that the flue and combustion chamber are fully de-pressurized and isolated before beginning cleaning. Follow local codes and the equipment manufacturer service procedures when performing combustion-system maintenance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBristle Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 42 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBristle Material\u003c\/strong\u003e: Fiber\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: Standard Wood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.45 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: 76235\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51540329398578,"sku":"76235","price":20.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d767c831e3ddeb9bfe173600df079516.jpg?v=1785852366","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-76235-boiler-furnace-fiber-brush","provider":"Voomi Supply","version":"1.0","type":"link"}
