The brush measures 13\/16 inches in diameter with a 6-1\/4 inch overall length and a 4-inch brush length. Nylon bristles provide effective scrubbing action while remaining gentle enough for use on tube walls where metal bristles could cause damage. The 12-24 female threaded connection allows attachment to standard extension rods for deeper tube access. HVAC service technicians and refrigeration mechanics use this brush as part of routine condenser maintenance.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for residential and light commercial HVAC systems requiring periodic condenser tube cleaning. It is commonly used during scheduled maintenance on chilled water systems, heat exchangers, and condensing units where fouling, scale, or debris accumulation inside tubes reduces heat transfer efficiency. The spiral stem design helps work bristles along the tube wall as the brush is rotated and pushed through the tube. It ships individually and is available in single-unit quantities, making it practical for service vans and small-shop restocking.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e13\/16 inches brush diameter sized for standard condenser tube bores\u003c\/li\u003e\n  \u003cli\u003e6-1\/4 inch overall length with a 4-inch active brush section\u003c\/li\u003e\n  \u003cli\u003eNylon bristles resist corrosion and are safe for use on soft tube materials\u003c\/li\u003e\n  \u003cli\u003e12-24 female threaded connection for use with standard extension rods\u003c\/li\u003e\n  \u003cli\u003eSingle stem spiral construction promotes consistent bristle contact along tube walls\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds, suitable for field carry in a service kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement brush for HVAC and refrigeration condenser tube cleaning applications requiring a 13\/16 inch diameter spiral brush with a 12-24 female threaded connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAlways de-energize and lock out the unit before accessing condenser tubes for cleaning. Attach the brush to a compatible 12-24 threaded extension rod before inserting into the tube. Use steady rotational and linear motion to work the brush through the tube without forcing or bending the stem. Follow applicable ASHRAE and equipment manufacturer maintenance guidelines when performing condenser cleaning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 13\/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: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush 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: 43725\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51538918539570,"sku":"43725","price":15.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3a0241527cd90f68c8d2d1a8be755d08.jpg?v=1785829606","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-43725-condenser-tube-brush-nylon-13-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
