Built with nylon bristles, it removes scale, biofilm, and debris from tube walls without abrading softer metals. The brush measures 9\/16 inch in diameter and 6.25 inches overall, with a brush and scraper length of 4 inches. The male connection end allows it to attach to standard extension rods for deeper reach. HVAC technicians and refrigeration mechanics reach for this tool during routine condenser maintenance and system clean-outs.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for residential and light commercial HVAC applications where condenser tube cleaning is part of scheduled preventive maintenance or system restoration. It fits tubes sized for a 9\/16 inch brush diameter, making it appropriate for smaller-bore condenser and chiller tube bundles. The nylon bristle construction is compatible with copper, aluminum, and other non-ferrous tube materials commonly found in split-system and packaged cooling equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle stem spiral design maintains consistent bristle contact along the full 4 inch brush length\u003c\/li\u003e\n  \u003cli\u003eNylon bristles clean effectively without scratching or corroding non-ferrous tube walls\u003c\/li\u003e\n  \u003cli\u003e9\/16 inch diameter fits standard small-bore condenser and heat exchanger tubes\u003c\/li\u003e\n  \u003cli\u003eMale connection end compatible with standard cleaning rod extensions\u003c\/li\u003e\n  \u003cli\u003e6.25 inch overall length provides direct access without an extension in shallow tube sheets\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds for easy single-hand use during service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style cleaning accessory for condenser tubes and heat exchanger tube bundles requiring a 9\/16 inch diameter brush.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCondenser tube brushes are typically used by HVAC technicians and refrigeration mechanics during planned maintenance or corrective service. Before brushing, shut down and lock out the unit per OSHA lockout\/tagout procedures and relieve any system pressure where applicable. Insert the brush into the tube with steady, even strokes and avoid forcing an oversized brush into an undersized tube, as this can damage tube walls. Pair with appropriate extension rods when tube depth exceeds the brush overall length.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 9\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.25 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: 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\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: 93713\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51541745303858,"sku":"93713","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/252c335a9631ac0cce5c1a09d7bd3fa5.jpg?v=1785883782","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-93713-condenser-tube-brush-9-16-in-nylon","provider":"Voomi Supply","version":"1.0","type":"link"}
