The spiral stem construction holds stainless steel bristles securely, delivering consistent scrubbing action throughout the full brush length. At 11\/16 inches in diameter and 6 inches overall length with a 4-inch brush length, this tool reaches into confined passages where standard cleaning tools cannot. The 12-24 female threaded connection allows attachment to extension rods or powered handles. Plumbers, HVAC technicians, and industrial maintenance technicians are the primary installers and users of this brush type.\u003c\/p\u003e\n\u003cp\u003eThis tube brush is suited for light to moderate deburring, fouling removal, and surface preparation inside metal tubing in both residential and light commercial applications. The stainless steel bristles resist corrosion, making the brush appropriate for use in wet environments or on stainless, copper, and similar metal tube interiors. The 12-24 female threaded connection is a standard thread size compatible with common brush extension rod systems, supporting use in boiler tubes, heat exchanger passages, condenser tubes, and drain lines of comparable bore size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble stem spiral construction keeps bristles evenly distributed for consistent contact along the tube wall\u003c\/li\u003e\n  \u003cli\u003eStainless steel bristles resist corrosion and hold up in wet or chemically active environments\u003c\/li\u003e\n  \u003cli\u003e11\/16-inch brush diameter sized for small-bore tube and pipe cleaning applications\u003c\/li\u003e\n  \u003cli\u003e4-inch brush length provides effective scrubbing reach inside confined passages\u003c\/li\u003e\n  \u003cli\u003e12-24 female threaded connection accepts standard extension rods for added reach\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.14 pounds for comfortable single-hand use or powered drive operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-service tube brush for use in applications requiring an 11\/16-inch diameter spiral brush with a 12-24 female threaded connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis brush is installed by threading the 12-24 female end onto a compatible extension rod or drill chuck adapter before inserting into the tube bore. Verify the bore diameter matches the brush diameter before use to avoid bristle damage or brush lodging. When used with a powered driver, run at low speed and avoid forcing the brush into bends that exceed the brush flexibility. Always wear appropriate eye protection when operating tube brushes in open tube ends.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Double Stem Spiral Tube Brush\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 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: Female\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 12-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: 43819\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51543571530034,"sku":"43819","price":27.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb4d67c506d789222b588febadf221fb.jpg?v=1785920490","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-43819-spiral-tube-brush-11-16-in-6-in-oal-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
