The brush measures 5\/16 inch in diameter with an overall length of 4-1\/2 inches and a brush or scraper length of 3 inches. Nylon bristles provide effective mechanical scrubbing action to remove scale, deposits, and debris from tube walls without damaging softer tube materials. The 8-32 male threaded connection allows the brush to attach to compatible extension rods for deeper tube access. HVAC technicians and refrigeration service pros use this brush during routine condenser maintenance to restore heat-transfer efficiency.\u003c\/p\u003e\n\u003cp\u003eThis tube brush is suited for residential and light commercial condenser tube cleaning applications. It is commonly used during scheduled maintenance on shell-and-tube condensers, evaporator coils with accessible tube sheets, and similar heat exchanger components. The nylon bristle construction makes it appropriate for aluminum, copper, and other non-ferrous tube materials where wire bristles could cause surface damage or galvanic concerns. The compact overall length and threaded male connection make it easy to use with standard brush extension rod systems found in most HVAC service kits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16 inch brush diameter sized for standard small-bore condenser tubes\u003c\/li\u003e\n  \u003cli\u003eNylon bristles resist corrosion and are safe for non-ferrous tube materials\u003c\/li\u003e\n  \u003cli\u003e3 inch brush length delivers concentrated scrubbing action along the tube bore\u003c\/li\u003e\n  \u003cli\u003e8-32 male threaded connection for use with compatible extension rod systems\u003c\/li\u003e\n  \u003cli\u003e4-1\/2 inch overall length for controlled handling in tight service panels\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.04 pounds, easy to carry in a field service bag\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement brush for use with standard 8-32 threaded condenser tube brush extension rods used in HVAC and refrigeration tube-cleaning applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this brush should be performed by qualified HVAC or refrigeration technicians. Before cleaning condenser tubes, isolate and de-energize the system and relieve any residual system pressure per standard lockout\/tagout procedures. Thread the brush securely onto a compatible 8-32 extension rod before inserting into the tube bore, and withdraw the brush straight to avoid bristle deformation. Do not force an oversized brush through a tube smaller than the rated diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Single Stem Spiral Condenser Tube Brush\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Length\u003c\/strong\u003e: 3 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: Male threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 93703\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51542321332530,"sku":"93703","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35e7004c88beea1105d96a456a8529fa.jpg?v=1785898085","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-93703-condenser-tube-brush-5-16-in-nylon","provider":"Voomi Supply","version":"1.0","type":"link"}
