With a 3-inch diameter head and a 27-inch overall length, it provides the reach and scrubbing surface needed to clear scale, soot, and debris from tube interiors without damaging the surrounding metal. This type of hand tool is a standard item in the service kit of licensed boiler technicians and HVAC service professionals who perform routine boiler maintenance and combustion-side cleaning.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for residential and light commercial boiler service work. The 3-inch diameter makes it appropriate for fire-tube boiler flue passages of that bore size. The 27-inch overall length gives the technician adequate reach into longer tube runs without requiring extension handles in most standard applications. It is used during annual boiler tune-ups, pre-season inspections, and after-combustion cleanouts where soot accumulation reduces heat transfer efficiency.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePatent fiber fill resists heat and moisture common in boiler flue environments\u003c\/li\u003e\n  \u003cli\u003e3-inch diameter head matches standard fire-tube boiler flue bore sizes\u003c\/li\u003e\n  \u003cli\u003e27-inch overall length provides reach into tube runs without extension hardware\u003c\/li\u003e\n  \u003cli\u003eHand tool design requires no power source — ready for immediate field use\u003c\/li\u003e\n  \u003cli\u003eConsistent brush diameter maintains contact with tube walls for effective scale and soot removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement boiler brush suitable for cleaning fire-tube boiler flue passages and heat exchanger tubes with a 3-inch bore diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eBoiler cleaning should be performed by a qualified HVAC or boiler technician following lockout\/tagout procedures with the boiler fully shut down and cooled. Confirm the flue passage diameter before selecting a brush to avoid forcing an oversized brush that could damage tube seats. Wear appropriate PPE including eye protection and gloves when clearing soot and combustion deposits. Local codes and manufacturer service manuals should be consulted for complete boiler maintenance procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 27 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Patent Fiber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 038091399758\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MILL-ROSE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 39975\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILL-ROSE","offers":[{"title":"Default Title","offer_id":51673144328498,"sku":"39975","price":14.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/mill-rose-39975-fiber-boiler-brush-3-in-27-in-oal","provider":"Voomi Supply","version":"1.0","type":"link"}
