The brush head measures 8 inches in diameter and 4.5 inches in brush length, with a 7-inch overall length that provides good reach into standard-depth openings. Nylon fill material makes it suitable for surfaces where wire bristles could cause damage or contamination. The 0.25-inch stainless steel shank connects to standard drill chucks or flexible drive extensions, making it practical for both hand and power-assisted use. HVAC technicians, plumbers, and maintenance professionals use this brush for tube cleaning in heat exchangers, condenser coils, and piping systems.\u003c\/p\u003e\n\u003cp\u003eThis tube brush is suited for residential and light commercial maintenance tasks where internal bore cleaning is required. Typical applications include cleaning heat exchanger tubes, evaporator drain pans, pipe interiors, and conduit openings. The nylon fill is non-abrasive and resistant to many common cleaning chemicals, making it a practical choice when working around copper tubing, aluminum surfaces, or other soft metals. The stainless steel shank adds durability when the brush is used with a power drill or flex shaft.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8-inch brush diameter for cleaning larger-bore tubes and pipe interiors\u003c\/li\u003e\n  \u003cli\u003eSingle-spiral construction for consistent radial contact along the full brush length\u003c\/li\u003e\n  \u003cli\u003eNylon fill material resists corrosion and is safe on soft metal surfaces\u003c\/li\u003e\n  \u003cli\u003e0.06-inch filament diameter provides firm yet non-damaging bristle action\u003c\/li\u003e\n  \u003cli\u003e0.25-inch stainless steel shank compatible with standard drill chucks and flex drive tools\u003c\/li\u003e\n  \u003cli\u003e7-inch overall length for reach into standard tube depths\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service brush for use in residential and commercial tube-cleaning applications where an 8-inch diameter single-spiral nylon brush with a 0.25-inch shank is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis brush is typically used by HVAC technicians and plumbers during scheduled maintenance or system servicing. Before inserting the brush into any tube or heat exchanger, shut down and de-energize the associated system per local codes and manufacturer guidance. When using with a power drill, start at low RPM to verify brush tracking before increasing speed. Do not force an oversized brush into a tube bore, as this can damage both the brush filaments and the tube wall.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilament Diameter\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 pounds\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: SCHAEFER BRUSH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 42630\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51541310472498,"sku":"42630","price":81.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f1617eacc0590fa803aa421a0feac021.jpg?v=1785872059","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-42630-nylon-tube-brush-8-in-single-spiral","provider":"Voomi Supply","version":"1.0","type":"link"}
