The spiral construction drives the stainless steel bristles firmly against bore walls, removing scale, debris, and buildup without collapsing under pressure. At 7.25 inches overall length with a 4.5-inch brush section and a 1.25-inch diameter, this brush is sized for standard small-bore tube and pipe applications. The 0.25-inch NPSM male connection allows it to mount directly to a rod, handle, or drill chuck. Stainless steel construction throughout resists corrosion, making it suitable for wet, chemical, or high-temperature service environments.\u003c\/p\u003e\n\u003cp\u003eThis brush is used in HVAC, plumbing, and industrial maintenance work where bore cleanliness is critical. Common applications include cleaning condenser tubes, evaporator coils, copper refrigerant lines, drain lines, and small-diameter pipe fittings before soldering or inspection. The stainless steel bristle fill holds up in caustic or high-moisture environments where carbon steel brushes corrode or shed. Service technicians and pipefitters reach for this brush during scheduled maintenance, pre-solder prep, and inspection cycles on residential and light commercial systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble stem spiral design maintains bristle contact with tube bore walls throughout the full stroke\u003c\/li\u003e\n  \u003cli\u003eStainless steel bristles resist corrosion in wet, chemical, and high-temperature environments\u003c\/li\u003e\n  \u003cli\u003e1.25-inch brush diameter suited for standard small-bore tube and pipe cleaning\u003c\/li\u003e\n  \u003cli\u003e4.5-inch brush length provides extended reach inside tubes and fittings\u003c\/li\u003e\n  \u003cli\u003e0.25-inch NPSM male connection mounts to standard rods, handles, or drill chucks\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.38 pounds for easy single-hand operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-use tube brush for 1.25-inch inside-diameter tubes, pipes, and fittings in HVAC, plumbing, and industrial maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis brush is installed and used by HVAC technicians, plumbers, and maintenance professionals. Before brushing any tube or fitting connected to a live system, shut off all fluid flow and depressurize the line. The 0.25-inch NPSM male thread should be hand-tightened onto the extension rod or handle before use to avoid cross-threading. Do not force the brush through bends tighter than the bristle section will naturally follow, as this can deform the stem or loosen the fill.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Section Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBristle Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: NPSM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Gender\u003c\/strong\u003e: Male\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 pounds\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: SCHAEFER BRUSH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 43836\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51539015762226,"sku":"43836","price":30.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2536226e1c04d2ae19e7396860474017.jpg?v=1785832914","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-43836-spiral-tube-brush-1-1-4-in-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
