The stainless steel bristles provide aggressive scrubbing action suited for removing scale, debris, and buildup from metal surfaces. At 11\/16 inch in diameter and 6-1\/4 inches in overall length, with a 4-inch brush length, this tool fits into tight access points where standard brushes cannot reach. The 12-24 female threaded connection allows the brush to be mounted on compatible extension rods or cleaning equipment handles.\u003c\/p\u003e\n\u003cp\u003eThis tube brush is used in HVAC, plumbing, refrigeration, and light industrial service applications. It is well suited for cleaning heat exchanger tubes, condenser tubes, boiler flues, and similar cylindrical passages during routine maintenance or system overhaul. Technicians in mechanical and facilities trades rely on this size for small-diameter tube cleaning tasks. The stainless steel construction holds up to repeated use in environments where corrosion resistance is important.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble stem, single spiral construction provides consistent bristle contact along the tube wall\u003c\/li\u003e\n  \u003cli\u003eStainless steel bristles resist corrosion and maintain shape through repeated use\u003c\/li\u003e\n  \u003cli\u003e11\/16 inch brush diameter fits small-bore tubes and passages\u003c\/li\u003e\n  \u003cli\u003e4-inch brush length covers adequate cleaning area per stroke\u003c\/li\u003e\n  \u003cli\u003e12-24 female threaded connection compatible with standard extension rod systems\u003c\/li\u003e\n  \u003cli\u003eCompact 6-1\/4 inch overall length suits tight-space applications\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 brush handles.

Insert the brush into the tube with steady, even pressure and avoid forcing the bristles at sharp angles, which can deform the spiral. Wear appropriate hand and eye protection when cleaning tubes that may contain scale or chemical residue. Inspect bristle condition periodically and replace the brush when bristles show significant wear or deformation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 11\/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\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: 43519\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51539000525106,"sku":"43519","price":31.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fb81d824d4bd43b2aea79e6180e3d562.jpg?v=1785832387","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-43519-tube-brush-11-16-in-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
