The brush features nylon bristles mounted on a spiral stem, providing effective mechanical cleaning of tube inner walls without damaging the tube surface. At 0.75 inches in diameter and 6.25 inches overall length, with a 4-inch brush section, this tool is sized for standard condenser tube bore diameters. The 12-24 female connection allows it to be threaded onto compatible extension rods for deeper tube access. HVAC technicians and refrigeration mechanics keep this brush in regular rotation during condenser cleaning and maintenance services.\u003c\/p\u003e\n\u003cp\u003eThe 43722 is suited for residential and light commercial HVAC condenser cleaning applications. It is used to remove scale, debris, and biological buildup from the inner walls of condenser tubes in shell-and-tube heat exchangers and similar equipment. The nylon bristle construction makes it appropriate for use on copper and aluminum tube materials where metal bristles could cause scoring or galvanic concerns. It is commonly deployed during seasonal maintenance, coil cleaning, and system efficiency restoration work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.75 inch brush diameter fits standard condenser tube bore sizes\u003c\/li\u003e\n  \u003cli\u003eNylon bristles clean effectively without scoring tube walls\u003c\/li\u003e\n  \u003cli\u003e4-inch brush length covers adequate contact area per pass\u003c\/li\u003e\n  \u003cli\u003e6.25 inch overall length provides direct access without extension for short tube runs\u003c\/li\u003e\n  \u003cli\u003e12-24 female threaded connection accepts standard extension rod sets\u003c\/li\u003e\n  \u003cli\u003eSingle stem spiral design maintains bristle contact around the full tube circumference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style cleaning brush for condenser tubes measuring approximately 0.75 inches in inner diameter, compatible with standard 12-24 threaded extension rods used in HVAC and refrigeration tube cleaning systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed HVAC technician or refrigeration mechanic should de-energize and lock out the system before performing condenser tube cleaning. Ensure refrigerant pressure is relieved and the system is properly isolated before accessing tube sheets or heat exchanger internals. Thread the brush securely onto the extension rod before insertion to prevent disconnection inside the tube. Follow applicable mechanical codes and manufacturer service procedures for the specific equipment being serviced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 0.75 inches\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: 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: 43722\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51541579202866,"sku":"43722","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c031e2931a1c7eaeed25a4f5b5637b5.jpg?v=1785879740","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-43722-condenser-tube-brush-nylon","provider":"Voomi Supply","version":"1.0","type":"link"}
