The brush features stainless steel bristles wound in a spiral pattern around a stainless steel double stem core, delivering durable scrubbing action in demanding cleaning applications. With a 7\/16 inch brush diameter and 6 inch overall length, including a 4 inch brush section, it fits a range of small-diameter openings. The 12-24 female threaded connection allows it to attach to standard extension rods for extended reach. Weighing 0.1 pounds, it is light enough for frequent hand use by HVAC technicians, plumbers, and maintenance professionals.\u003c\/p\u003e\n\u003cp\u003eThis tube brush is suited for residential and light commercial maintenance tasks where small-diameter passages require periodic cleaning. Common applications include cleaning heat exchanger tubes, condenser tubes, drain lines, and similar bore passages encountered during HVAC, plumbing, and general mechanical service work. The stainless steel construction makes it appropriate for use in environments where corrosion resistance matters, including wet or chemical-exposed service conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble stem spiral construction provides consistent contact with tube walls throughout the brush length\u003c\/li\u003e\n  \u003cli\u003eStainless steel bristles resist corrosion and hold up to repeated use in wet or chemically active environments\u003c\/li\u003e\n  \u003cli\u003eStainless steel core and stem for full corrosion resistance throughout the assembly\u003c\/li\u003e\n  \u003cli\u003e7\/16 inch brush diameter fits small-bore tubes and passages common in HVAC and plumbing systems\u003c\/li\u003e\n  \u003cli\u003e4 inch brush section within a 6 inch overall length for effective reach into confined spaces\u003c\/li\u003e\n  \u003cli\u003e12-24 female threaded connection for attachment to standard extension rods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-purpose tube brush for use with standard 12-24 threaded extension rod systems in HVAC, plumbing, and industrial maintenance applications requiring a 7\/16 inch brush diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis brush is installed by hand or with a compatible 12-24 threaded extension rod — no power tools are required for attachment. Before use in a live system, shut off fluid flow and depressurize or drain the line as required by the applicable service procedure. Avoid forcing the brush through passages significantly smaller than the rated 7\/16 inch diameter, as this can damage bristles or deform the stem. Inspect bristles for wear or splaying after extended use and replace when cleaning effectiveness drops.\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: 7\/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 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\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: 43807\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51542092906802,"sku":"43807","price":30.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4bfd9faf4a4fe1dd68221e0195b93265_18f7969f-69b5-4568-8c81-512da1c23b7b.jpg?v=1785891834","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-43807-spiral-tube-brush-7-16-in-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
