Built with nylon bristles, it scrubs tube walls without scratching or corroding metal surfaces. The brush measures 3\/4 inch in diameter and 6-1\/4 inches in overall length, with a brush scraper length of 4 inches. The male connection end allows the brush to be attached to a standard extension rod for deeper tube access. HVAC technicians and refrigeration service pros use this tool as part of routine condenser maintenance to restore heat transfer efficiency and clear fouling from tube interiors.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for use in residential and light commercial HVAC systems, chiller tube bundles, and refrigeration condenser coils where 3\/4 inch tube bores are present. It fits standard tube cleaning rod setups and is practical for use during scheduled preventive maintenance or after-season condenser cleaning. The nylon bristle construction makes it appropriate for copper, aluminum, and light-gauge steel tubes where wire bristles would be too aggressive.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch brush diameter sized for standard condenser tube bores\u003c\/li\u003e\n  \u003cli\u003eNylon bristles resist corrosion and are safe for soft tube materials including copper and aluminum\u003c\/li\u003e\n  \u003cli\u003e4 inch brush scraper length provides effective contact area inside the tube\u003c\/li\u003e\n  \u003cli\u003e6-1\/4 inch overall length with male connection end for rod attachment and extended reach\u003c\/li\u003e\n  \u003cli\u003eSingle stem spiral construction maintains consistent bristle contact along the tube wall\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds, easy to handle during repeated cleaning passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style cleaning accessory for condenser tube maintenance applications requiring a 3\/4 inch diameter tube brush with a male connection end compatible with standard tube cleaning rod extensions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis brush is installed by HVAC technicians and refrigeration service technicians as part of condenser tube cleaning procedures. Always isolate and de-energize the system and relieve any system pressure before accessing the condenser tube bundle. Attach the brush to a compatible cleaning rod using the male connection end before inserting it into the tube bore. Do not force the brush into tubes smaller than the rated diameter, as this will damage bristles and may score the tube wall.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 3\/4 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: Male\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: 93722\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51543185916210,"sku":"93722","price":15.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8c2370c21e57d7fa25cdae20b453893.jpg?v=1785916657","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-93722-condenser-tube-brush-3-4-in-nylon","provider":"Voomi Supply","version":"1.0","type":"link"}
