With a 11\/16 inch brush diameter and a 6-1\/4 inch overall length, it reaches into standard condenser tube bores to remove scale, biofilm, and debris that restrict heat transfer. The brush body and bristles are constructed from nylon, making it resistant to corrosion and compatible with wet cleaning environments. The 12-24 female threaded connection allows it to attach to standard extension rods for deeper reach into tube sheets. HVAC technicians and refrigeration service pros use this brush during routine condenser maintenance and coil cleaning procedures.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for residential and light commercial HVAC systems, chiller tube bundles, and heat exchanger condenser tubes where interior tube cleaning is required. The spiral stem design works the nylon bristles against tube walls as the brush is advanced and rotated, dislodging fouling without scratching copper or steel tube interiors. It is appropriate for use during seasonal maintenance, system recommissioning, or troubleshooting reduced system efficiency caused by tube fouling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e11\/16 inch brush diameter sized for standard condenser tube bores\u003c\/li\u003e\n  \u003cli\u003eNylon bristles and brush body resist corrosion in wet service conditions\u003c\/li\u003e\n  \u003cli\u003eSpiral stem design agitates tube walls for thorough fouling removal\u003c\/li\u003e\n  \u003cli\u003e12-24 female threaded connection compatible with standard extension rods\u003c\/li\u003e\n  \u003cli\u003e6-1\/4 inch overall length with 4 inch brush\/scraper length for effective tube reach\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds for easy single-hand operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in condenser tubes accepting an 11\/16 inch diameter brush with a 12-24 female threaded connection.

Thread the brush onto a compatible 12-24 male extension rod before inserting into the tube bore. Advance and rotate the brush with steady, even strokes to avoid bending the stem. Follow applicable safety and environmental guidelines for collection and disposal of dislodged debris and cleaning fluids.\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\/Scraper Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBristle Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush\/Scraper Material\u003c\/strong\u003e: Nylon\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: 43719\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51542277882162,"sku":"43719","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4ea5cd4d95a2528a7788309bf96ae96_beb5a51b-7ad0-45dd-884a-15057177c2ae.jpg?v=1785897138","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-43719-condenser-tube-brush-11-16-in-nylon","provider":"Voomi Supply","version":"1.0","type":"link"}
