The brush measures 15\/16 inches in diameter with an overall length of 6-1\/4 inches and a brush length of 4 inches. Bristles and brush construction are stainless steel throughout, making the 43531 suitable for applications involving moisture, mild chemicals, or residues that would corrode standard carbon steel brushes. The 12-24 female threaded connection allows the brush to attach to standard extension rods and drill adapters commonly used by HVAC technicians, plumbers, and maintenance professionals.\u003c\/p\u003e\n\u003cp\u003eThis tube brush is suited for light-duty to medium-duty cleaning of small-diameter tubes found in heat exchangers, condenser coils, boiler tubes, and copper or steel piping. The 15\/16-inch diameter makes it appropriate for cleaning tube IDs in the 7\/8-inch to 15\/16-inch range. Stainless steel construction handles contact with water, condensate, scale, and light corrosion deposits without shedding or premature bristle failure. Ideal for periodic maintenance cleaning by HVAC service technicians and plumbing contractors.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e15\/16 inches diameter for precise fit in small-bore tube cleaning applications\u003c\/li\u003e\n  \u003cli\u003e4-inch brush length provides effective scrubbing coverage in a single pass\u003c\/li\u003e\n  \u003cli\u003eStainless steel bristles resist corrosion and bristle fatigue in wet environments\u003c\/li\u003e\n  \u003cli\u003eDouble stem, single spiral construction maintains brush shape under use pressure\u003c\/li\u003e\n  \u003cli\u003e12-24 female threaded connection is compatible with standard extension rods and power drill adapters\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.16 pounds for easy handling in confined spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 12-24 threaded extension rods and adapters.

Isolate or shut off the system being serviced and allow components to cool before inserting the brush into any tube or heat exchanger. Use appropriate personal protective equipment when working with scale, debris, or chemical residues dislodged during cleaning. Inspect bristles for wear or distortion after each use and replace the brush if the diameter has reduced significantly or bristles show breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Length\u003c\/strong\u003e: 4 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 Threaded\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: 0.16 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: 43531\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51541969240370,"sku":"43531","price":22.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/368775da317bfbc9d82e684fecc697c7.jpg?v=1785888612","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-43531-tube-brush-15-16-in-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
