The brush features a 0.5-inch brush diameter with a 3-inch brush length and an 8.5-inch overall length, making it well-suited for reaching into confined tubing without requiring disassembly of surrounding components. The nylon fill material resists moisture and many chemicals, making it appropriate for use in wet or chemically active environments. The 0.125-inch shank diameter allows the brush to be chucked into a standard hand drill or used manually. HVAC technicians, plumbers, and general maintenance professionals reach for this style of brush during tube cleaning and deburring tasks.\u003c\/p\u003e\n\u003cp\u003eThis tube brush is used in applications where internal bore surfaces need to be cleaned, deburred, or prepped for connection. Typical scenarios include cleaning evaporator drain lines, small copper or plastic tubing ends, heat exchanger tubes, and instrument lines in both residential and light commercial settings. The nylon filaments are non-abrasive on softer tube materials, making this brush appropriate where steel wire would risk scratching or damaging the bore surface. The 0.010-inch filament diameter provides consistent, even contact across the tube wall without aggressive material removal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.5-inch brush diameter for standard small-bore tube cleaning\u003c\/li\u003e\n  \u003cli\u003eNylon fill material resists moisture and chemical exposure\u003c\/li\u003e\n  \u003cli\u003e0.010-inch filament diameter delivers even, non-abrasive contact\u003c\/li\u003e\n  \u003cli\u003e0.125-inch shank diameter fits standard drill chucks for power or manual use\u003c\/li\u003e\n  \u003cli\u003e8.5-inch overall length provides reach into recessed tube openings\u003c\/li\u003e\n  \u003cli\u003e3-inch trim length and 3-inch brush length for balanced cleaning coverage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-use tube brush for small-bore cleaning tasks in HVAC, plumbing, and industrial maintenance applications where a 0.5-inch diameter nylon brush is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis brush is installed by trade professionals including HVAC technicians and plumbers during routine maintenance or system prep work. Always ensure the tube or line being cleaned is depressurized and, where applicable, isolated from the system before inserting the brush. The shank may be used manually or secured in a hand drill at low speed for more thorough cleaning. Avoid exceeding the brush diameter rating, as forcing an oversized brush into a smaller bore will damage the filaments and may restrict the bore.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrim Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilament Diameter\u003c\/strong\u003e: 0.010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 47131600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: NORTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66252838820\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539160891698,"sku":"66252838820","price":23.35,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c1f9dc19d8da9d21bd49607c6aa1109.jpg?v=1785835680","url":"https:\/\/voomisupply.com\/products\/norton-66252838820-gemini-nylon-tube-brush-0-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
