The brush features nylon bristles mounted on a spiral stem configuration, delivering consistent radial contact along the tube wall to dislodge scale, biofilm, and debris. At 11\/16 inches in diameter and 6.25 inches overall length, with a 4-inch brush section, this tool is sized for standard condenser tube bores common in commercial and residential cooling equipment. The male connection end allows direct attachment to standard brush extension rods. HVAC technicians and refrigeration service pros keep this brush in rotation for routine condenser maintenance.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for routine tube-side maintenance on shell-and-tube condensers, evaporator coil headers, and similar heat exchanger tube bundles. It performs well in both residential and light commercial HVAC applications where tube diameters in the 11\/16-inch range are encountered. The nylon bristle material is appropriate for aluminum, copper, and other soft-metal tube interiors where aggressive wire bristles could cause surface damage. It is typically used during seasonal maintenance shutdowns or as part of a planned preventive maintenance schedule.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle stem spiral design provides consistent radial bristle contact along the tube bore\u003c\/li\u003e\n  \u003cli\u003eNylon bristles resist corrosion and are safe for use on soft-metal tube interiors\u003c\/li\u003e\n  \u003cli\u003e11\/16-inch brush diameter sized for standard condenser tube bores\u003c\/li\u003e\n  \u003cli\u003e4-inch brush length covers adequate tube surface per stroke\u003c\/li\u003e\n  \u003cli\u003eMale connection end compatible with standard extension rod systems\u003c\/li\u003e\n  \u003cli\u003e6.25-inch overall length allows controlled single-hand operation in tight spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and service brush for HVAC and refrigeration condenser tube cleaning applications requiring an 11\/16-inch diameter nylon brush with a male connection end.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTube brush service is typically performed by licensed HVAC or refrigeration technicians during scheduled maintenance. Shut down and isolate the refrigeration or chiller circuit and relieve any system pressure before accessing condenser tubes. Attach the brush to an appropriate extension rod before inserting into the tube bore, and work the brush through the full length of the tube using consistent strokes. Do not force an oversized brush into an undersized tube bore, as this can damage tube walls or deform bristles.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Length\u003c\/strong\u003e: 4 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\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  \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: 93719\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51543464116530,"sku":"93719","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f34eeafb104ae40a0651679cb8b8eb9c.jpg?v=1785919000","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-93719-condenser-tube-brush-11-16-in-nylon","provider":"Voomi Supply","version":"1.0","type":"link"}
