It features stainless steel bristles mounted on a stainless steel double stem construction, delivering durability in both dry and wet cleaning environments. The brush measures 3\/8 inch in diameter with a 6-inch overall length and a 4-inch brush length, making it well suited for reaching into tight passages. It connects via a 12-24 female thread, allowing it to be driven by compatible extension handles or drill attachments. HVAC technicians, plumbers, and maintenance professionals regularly use this tool for tube cleaning, port maintenance, and surface preparation tasks.\u003c\/p\u003e\n\u003cp\u003eThis brush is appropriate for residential and commercial service work where consistent bore cleaning is required. Typical applications include cleaning condenser tubes, heat exchanger passages, small-diameter pipe fittings, and other tubular components where debris, scale, or fouling must be removed before service or inspection. The stainless steel construction resists corrosion and holds up under repeated use with common cleaning solutions. The 12-24 female threaded connection makes it compatible with standard extension rod systems used in tube and pipe cleaning setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble stem spiral construction provides consistent contact with tube interior walls\u003c\/li\u003e\n  \u003cli\u003eStainless steel bristles resist corrosion and hold up under repeated use\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch brush diameter fits small-bore tubes and ports\u003c\/li\u003e\n  \u003cli\u003e4-inch brush length with 6-inch overall length for reach into confined passages\u003c\/li\u003e\n  \u003cli\u003e12-24 female threaded connection for use with standard extension handles or power drive adapters\u003c\/li\u003e\n  \u003cli\u003eStainless steel stem and brush material throughout for uniform durability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 12-24 threaded extension rod systems.

Ensure the threaded connection is fully engaged before use to prevent the brush from detaching during operation. When using with power equipment, start at low speed to confirm the brush seats correctly in the tube bore. Disconnect any power source or drive tool before changing brushes or extension rods.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 3\/8 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 and Stem 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: 0.1 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: 43804\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51542945923378,"sku":"43804","price":30.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87c2d493d6b7319b32ce56d691cfa7e2.jpg?v=1785911885","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-43804-spiral-tube-brush-3-8-in-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
